WHY WE ALL NEED 

BACK UP! 

Back Up! is the latest magazine written by the PROLiNK team to let you 

understand more about why Uninterruptible Power Supply (“also termed 

UPS”) products are so important for businesses and consumers. 

The magazine is termed simply as “Back Up” mainly because we intend 

to take all the confusion out of this seemingly complicated product type 

and make it much easier for the regular folks to understand. We’d also 

want to help our readers to be able to learn and know how best to select 

a product that will be catered to their needs. 

Besides UPS products, we’ll also take a closer look at some of the other 

IT products that will be useful in various home or work situations so YOU 

(the reader) can make better choices when selecting an IT product to use. 

We hope you’d find this inaugural issue truly beneficial and we definitely 

hope to bring you more interesting articles in the issues to come! 

Best Wishes for a Great New Year Ahead! 

Cheers, 

The PROLiNK Team

WHY WE ALL NEED 

BACK UP! 

(UPS PRODUCTS) 

In the modern society we live in today, electronics and computer equipment 

play an important role in our lives. It seems that everyone feels the need 

to be connected and most people own a computer, have a smartphone 

that has internet access and work off tablets or laptops. 

In less developed environments, people still remain dependent on basic 

computers, fans, fluorescent lights, air-conditioning units or heaters to 

maintain a comfortable habitable environment in their homes or offices. 

With all these electronic, electrical and computer equipment around us, 

it seems ever more important that a high quality, uninterrupted power 

supply is essential. However, almost all national grid supply systems 

are subject to interference from natural and industrial sources, and no 

electrical supply source is free from brown-outs, interference and voltage 

variations. 

The operations of electrical, electronic and computer equipment are 

vulnerable to many forms of phenomena that may result in excess 

voltage surges and spikes or voltage drops. In time sensitive and crucial 

applications such as financial or banking data centres, ATM machines, 

company data servers, as well as hospital and medical equipment, this 

may translate to major data losses, damage of the computer or electronic 

equipment and even the loss of human lives!

Understanding the severity of such situations will make us more aware 

of the need for protection, even in countries like Singapore where most 

people tend to take our stable electricity supply sources for granted. 

We’ve seen unfortunate situations happen in such developed countries - 

the last major power failure in Singapore on 29 June 2004 is estimated 

to have cost businesses some S$6 million in losses. According to a study 

conducted by researchers at Lawrence Berkeley National Laboratory in 

2005, electric power outages and blackouts cost America around $80 

billion annually. 

Countries like Bangladesh, Sri 

Lanka, Pakistan and India are 

constantly plagued by power 

outages due to the insufficient 

supplies of electricity and the high 

cost of power generation. 

Being adequately protected with 

the right equipment is important. 

When a power outage at the 

hosting facility for the OCBC Securities site caused the 2-hour downtime 

in the morning of 26 Jan 2012 in Singapore, all customer data remained 

protected with appropriate security measures and the trading system 

was fully restored within an hour after power was restored. 

UPS (Uninterruptible Power Supply) products are 

some of the most fail-proof options of providing 

protection for the operation of your critical and 

time sensitive applications. 

Depending on their power requirements, users 

can select the right kind of UPS products to ensure 

that they receive a high quality electrical supply source that adequately 

protects them from possible power disruptions and power spikes.

Besides protection from power failures, another good thing we’ve noted 

about having a UPS around is that most of them now come with a feature 

called an AVR (Auto Voltage Regulation). This feature automatically 

regulates and smoothens off the power supply from voltage fluctuations 

(140-300V) to provide your equipment with a constant voltage. So what 

does this do for our equipment? Basically, this means the lifespan 

and durability of your equipment is prolonged, and the stability of the 

equipment is maintained at all times. 

In a nutshell, the primary role of any UPS is to provide short-term power 

when the input power source fails. However, most UPS units are also 

capable in varying degrees of correcting common utility power problems: 

1. Voltage spike or sustained Overvoltage 

2. Momentary or sustained reduction in input voltage. 

3. Noise, defined as a high frequency transient or oscillation, 

usually injected into the line by nearby equipment. 

4. Instability of the mains frequency. 

5. Harmonic distortion: defined as a departure from the ideal 

sinusoidal waveform expected on the line. 

Besides the key benefits of getting a UPS, being able to manage it well 

is also very important. With technology improving at such a rapid pace, 

if we’re getting a professional system such as an Online UPS model, 

most of them available now also offer options where they can now be 

programmed to collect and report relevant information to the users. 

These include the monitoring of load levels, conducting of battery tests, 

scheduling shut downs and also triggering of alerts via SMS and email 

should there be any power failures or failures in any parts of the UPS 

system. 

With our high dependency on computer, electronic and electrical 

equipment, it’s important to find the right UPS to meet our specific 

needs or requirements. And, we’re about to simplify the whole process 

of selection for you in the upcoming articles. Read on to find out more.

HOW DO I KNOW WHICH I NEED? 

So, we all know now that we need a UPS. What comes next? It’s probably 

going to be the process of selection. 

But how do we know what we’ll need? 

For starters, if what you’ll need is basic protection for a simple PC 

running on dual-core or the latest i3/i5/i7 processors to provide power 

for probably around 30-45 minutes, you can consider an entry level 600VA 

Line Interactive UPS. However, for Pentium users, you might have to note 

that the power consumption is going to be higher, so your backup time 

might be reduced to just 10 minutes, or you’ll probably need to get a 

higher capacity UPS to ensure that you’ll have a longer backup. 

Line Interactive UPS models are relatively inexpensive and provide 

adequate support for basic computer equipment especially in homes or 

small offices. 

For larger equipment like servers or medical apparatus, critical and time 

sensitive applications, as well as for larger offices, Online UPS models 

are generally recommended as they can offer longer back up times and 

0ms of transfer time with no interruption to the power supply. 

Here’s a run-down of what you can expect from either of the systems:

LINE INTERACTIVE UPS 

As the prices of UPS technology have dropped 

over the years, this has become the most 

common type of UPS offered in the market. 

Line Interactive UPS models come with the 

technology called an AVR or Automatic Voltage 

Regulation. In addition to doing everything that 

the traditional old Standby UPS does, this type 

of UPS also monitors the level and quality of 

the power coming from the wall and does some power “cleaning” by 

regulating the voltage flow. 

It uses a transfer switch for a system bypass between the utility power 

and the battery backup. Line Interactive UPS system consists of an Auto 

Voltage Regulator (AVR), a converter (AC to DC, DC to AC) with battery 

charger, a battery and a communication port as an option.

When mains power is present, the power goes through via a 3 Step AVR 

which features 2 boosts and 1 buck to decrease or increase the line 

voltage supplied to the load. 

When a blackout occurs, the UPS uses a voltage-sensing transfer switch 

to draw power from the batteries, and provides a power backup of around 

10-45 minutes depending on the load. The use of the switch, however, 

results in an inevitable transfer time of 2-8 ms. 

In the event of a longer blackout, line interactive models with USB 

connection come with software to provide an option to shut down the 

connected equipment. In addition, this software can be used to monitor 

and log the status of the system information such as voltage, power 

supply, current draw and alarm history. 

The topology of the line interactive UPS models produces a Simulated 

Sine or Modified Square Wave form. This output waveform is similar to a 

square wave output except that the output goes to zero volts for a period 

of time before switching to positive and negative. Sensitive equipment 

like servers, laser printers, fluorescent lights and audio equipment are 

not recommended for use with this system as overheating or irregular 

operations may occur. Simulated waveforms generate more noise and 

harmonic distortion compared to the true sine wave system produced by 

an Online UPS system.

Line Interactive UPS models are a good choices for home or small 

office use due to its affordable price tags and reasonable back up times. 

However, they are suitable for applications where a fast transfer time is 

necessary since data can be lost if the UPS cannot transfer to battery 

backup in time. 

If you are a home or small office user, you can pick from the wide range of 

PROLiNK Line Interactive models available from those in 650VA capacities 

to 1000VA. A usual guideline would be to pick the basic model PRO700V/ 

VU if you need to connect 1 PC, PRO850VU/ SU if you are a supporting 2 

basic PCs or PC with higher specifications, or finally PRO1200SV/U if you 

need to support 3 PCs or a gaming PC with high specifications. 

We’ve placed a cool little table below for you to refer to so you’ll know 

which best to pick to suit your needs. Alternatively, you can check with 

our friendly local distributors or retailers for more information on the 

features and stocks available for these products.

ONLINE OR DOUBLE-CONVERSION UPS 

True Online UPS models use 

a technique known as double 

conversion to offer a steady 

power output. They are ideal for 

equipment that are sensitive to 

power fluctuations such as audio 

recording equipment, sound booths, 

servers, medical and diagnostic 

equipment, office telephone systems 

and printers. 

By using “double conversion”, the system output remains independent 

of any fluctuations in AC supply voltage and frequency variation is 

maintained with the limits. Online UPS systems use the power circuit 

and an inverter that changes the incoming AC power into DC power 

through a rectifier and reconverts the power back to the regulated AC 

through the inverter. This collective double conversion of AC to DC and 

DC to AC provides continuous power to the load both for conditioned 

power and protection from power outages. In addition, there is no break 

in the supply of power to the load during transfers to battery mode for 

back up. 

Online UPS models are also the preferred choice for long run 

applications because the inverter is designed for continuous operation 

and built to charge a higher capacity battery. Most of the Online UPS 

models also come with internet monitoring features as an option. With 

an additional SNMP card, a standardized communication system used 

on local and wide area networks, users can monitor and control UPS 

systems connected to it via the standard Transmission Control Protocol/ 

Internet Protocol (TCP/IP) connections.

Online UPS are preferred choices for servers and IT storage equipments, 

remote mobile telecommunications, medical applications, water 

treatment plants, scientific labs and even military applications. However, 

it comes at a higher cost and also generates a greater amount of heat. 

PROLiNK UPS models are available in rackmount or tower units from 

1kVA to 120kVA options, with a full range of accessories to support your 

needs. 

However, if you are getting larger UPS units, we’d recommend that you 

speak to our UPS specialists in each country to determine the right model 

for your needs. 

We’ve put a table below to give you a good idea of which models you’ll

WHAT’S MY POWER? 

A simple guide to determining your 

power backup needs 

We have gone through a lot of details on what a UPS does and how it 

operates. However, we still think it’s important to know what you’ll need 

to support your systems. 

For the Line Interactive UPS models, you can refer easily to the table 

of the 3 models we have available and check your system’s power 

requirements. As a guideline, our basic 600VA model can usually support 

one simple PC and monitor, and our 1000VA model should support up to 

a maximum of 3 basic PCs or one gaming PC system. 

If you’re thinking of getting an Online UPS for your office, the table 

below should be a useful guide to how many standard dual core or i3 

PCs (consists of a 19” monitor) our basic online UPS models should be 

able to support and their respective backup times. We also have an easy 

reference table for CCTV cameras.

UPS ACCESSORIES 

When and why you’ll need them 

There are several reasons why having just a UPS system alone may not 

meet all of your requirements. Accessories like SNMP cards, additional 

batteries and switches will complement your UPS the same way a 

mouse, keyboard and monitor typically complement a CPU, Since online 

UPS models are usually used with sensitive equipment, troubleshooting 

or maintenance usually needs to be done without having to shutdown 

or turn off the actual equipment. In such situations, accessories like 

Automatic Transfer Switches and Maintenance Bypass Switches may be 

required to switch the equipment’s power source to other backup units or 

to the mains power supply. 

UPS usually backs up critical loads such as 

the power source tied to an ATM or sensitive 

medical apparatus. Therefore, it’s essential that 

the performance of the UPS be monitored, but 

yet a true waste of manpower to have someone 

stationed in the UPS room just to look over the 

system. 

An item like a Simple Network Management Protocol (SNMP) card can 

be utilised in such cases where the company would like to monitor their 

UPS performance. An SNMP is a standardised communication system 

used on Local and Wide Networks (LANs/ WANs) to monitor and control 

hardware systems connected to it via Transmission Control Protocol / 

Internet Protocol (TCP/IP) connections. The SNMP uses hardware specific 

Management Information Bases (MIBs) to collect information from polled 

IP connections. These can be viewed on a Network Management Station 

(NMS) or high performance workstation with a fast CPU and extensive 

hard disk capacity running specific monitoring and controlling software. 

UPS ACCESSORIES 

22 


4/4/13 11:49 AM

SNMP accessories are also available just to monitor 

signal contacts. These can be used to capture the 

general operating status information and trigger 

alarm notifications. 

Another accessory used for monitoring is a 

MODBUS which is an openly published protocol 

used specifically within industrial environments. In a UPS installation, 

the protocols are used to monitor the status of the UPS, report alarm 

signals and allow integration into a BMS panel or otherwise.

Essential Networking Tools to Help 

You Win Your Battle 

In the earlier section, we’ve been talking a fair bit about back up and all 

the various UPS models available to keep your equipment safe, however, 

we’re also truly aware of how technology and the internet has changed 

the way in which we work. 

23 



4/4/13 11:49 AM

In today’s modern world, individuals feel the need to be constantly 

connected. We surf the internet and read emails with our tablets and 

mobile phones even while we’re travelling and most of us now carry 

multiple devices – smartphones, laptops and tablets. With the current 

speed at which business is being conducted, not staying connected could 

mean the loss of a business deal or the missing of important events 

and appointments. That’s why mobile networking tools have become so 

essential for many individuals – we need USB modems and routers that 

make staying connected much easier. 

With the costs of 3G data SIM cards getting cheaper and network speeds 

faster, it’s now easy for most travellers to purchase a prepaid data SIM 

card at the airports, and pop it into their mobile phones. However, if you 

have multiple devices which require connection to the internet, or if you 

are travelling in a small group but don’t want to purchase so many SIM 

cards for your stay, you can purchase a MiFi or a mobile WiFi hotspot. 

THE MOBILE ROAD WARRIOR 

24 


4/4/13 11:49 AM

PROLiNK has several options available for people who need such a 

device. The simplest model to use, PRT7001H HSPA+ Mobile WiFi 

Hotspot, just requires you to put in a working SIM card to allow the 

sharing of WiFi with up to 10 devices. It comes with a rechargeable 

battery that can last up to 4 hours of use, and can support speeds of up 

to 21.6Mbps. 

If you’re bringing along your laptop or power bank, PRT7002H 3G HSPA+ 

USB Modem Router is a good choice since it is more affordable and also 

support 21.6Mbps speeds but doesn’t come with its own battery. All you 

need to do is put in the SIM card, power it up with a power bank or your 

laptop’s USB port, and you can start sharing your WiFi. 

For travellers who do not want to purchase a SIM card, but instead 

want to make use of the wired internet connection in their hotel rooms 

to share WiFi to the rest of the devices, there’s also available options 

such as the WNR1004 which is a compact travel router that can support 

speeds of up to 300Mbps or the WNR1011 which can support speeds of 

up to 150Mbps. 

Besides LAN sharing, the WNR1011 also comes with its own 2400mAh 

battery which can double up as a power bank and it also supports 3G 

sharing via a USB dongle/ modem. This is an affordable and multifunctional 

option for users which want to use both 3G and LAN sharing 

while they are moving about. 

USB modems PHS300 and PHS600 that support speeds of up to 7.2Mbps 

and 21.6Mbps respectively are also readily available options if you just 

intend to use the 3G data SIMs for your laptop. 

PROLiNK is also a specialist in networking products, and has been 

supplying major telecommunications companies with reliable modems 

and routers since its inception in 1991. You can visit the PROLiNK

MAKING ECO-FRIENDLINESS 

A LITTLE PART OF OUR LIVES 

You may have wondered why we would change an attractively coloured box to one as drab as a brown box packaging. 

In PROLiNK ® , we take our care for the environment seriously. By changing all the boxes for our larger products to 

brown boxes, we have made our own stand in reducing waste and encouraging recycling efforts. A little change by 

each organisation definitely makes a difference. 

Do you know that simple product packaging choices, reusing, and recycling are all areas that can affect our lives and 

our earth? By choosing to pick a product packaged in a brown box, you can help do your own little bit to contribute 

in saving our earth. A brown box is eco-friendly and extremely easy to recycle. 

Make a Choice to Do Your Part for the Environment Today! 

Why did we decide to change 

our packages for LED Monitors 

and UPS boxes? 

1. These items are our biggest products and are usually not 

displayed directly on retail shelves. 

2. Brown boxes have been proven to be sturdy enough to 

keep our products safe during transportation. 

3. Brown boxes are extremely easy to recycle and reuse. 

Besides that, it leaves minimal impact on the environment.
