DELPHYS MX 

from 800 to 900 kVA 

Three-phase Uninterruptible Power Supplies

Three-phase 

UPS DELPHYS MX 

800 and 900 kVA 

the Mega Power protection up to 5.4 MVA 

Based on the technology of the 500 kVA ad 

enhanced upon, the DELPHYS MX 800 and 

900 kVA is capable of a maximum system 

size of up to 5.4 MVA. 

The DELPHYS MX 800 and 900 kVA is 

specifically designed for demanding Data 

centre applications such as large DTC of 

banks/insurances, IDC, Telecom datacentres, 

semiconductor production lines and big 

automation manufactures, airports, big air 

traffic control centres, tunnels. 

DELPHYS MX, is a true-online “double 

conversion” UPS system which protects the 

load from power grid pollution or power failure, 

from utility power supply and diesel generators.

Three-phase 

UPS 


800 and 900 kVA 

Flexible architecture 

• Parallel system with modular units. 

• Powerful central bypass for power extension 

or redundancy. 

• Tier 3 and Tier 4 compatible. 

• Designed for optimal use with STS in 

downstream network. 

User-friendly operation and remote 

communication 

• Specially designed graphic touch screen for 

easy and ergonomic operation. 

• 7 com-slots plug-in communication interfaces 

for upgrading your operating requirements. 

• Easy remote monitoring via web browser or 

via customer’s supervision systems (web, 

intranet, extranet...). 

• Very open connectivity (Modbus/Jbus, Jbus 

tunnelling, LAN...). 

Easy to Service and Maintain 

• Front accessibility for all components. 

• Reduced MTTR thanks to extractible power 

bridges or Fans on “cassette”. 

• High reliability 

and availability 

• Lower Total Cost 

of Ownership 

• Easy to Service 

and Maintain 

• User-friendly operation and 

Remote Communication 

• Flexible

SYDIV 039 A GB 

High reliability and availability 

• Internal fault tolerant architecture with internal 

redundancies and fan failure localisation. 

• Intelligent embedded battery monitoring with 

failed block localisation and preventative 

remote alarm. 

• Able to withstand an output short circuit and 

overload, ensuring the systems safety under 

extreme conditions. 

• Reliable and robust paralleling mode. 

• Multisystem automatic cross synchronisation 

(ACS) for an optimised use with STS. 

• Output isolation transformer to reduce 

the influence of N-GND (Neutral Line-to- 

Ground) voltage and load harmonic current 

on UPS inverter. 

Lower Total Cost of Ownership 

• Minimised running costs, by: 

- Very high efficiency of up to 93.5% (lower 

energy dissipation and cooling costs) 

equals energy saving 

- ‘Energy saver’ on-line mode allows the 

number of running units of the system to 

adapt automatically to the real load 

- Free cooling compatible to save cooling 

costs. 

• Valuable space saving with its reduced 

footprint and exceptional high power density 

(the most compact unit of its class): 900 

kVA in less than 3.2 meters (width) per unit 

including the by-pass. DELPHYS MX units 

can also be installed without side or rear 

access (dependant on requirements). 

• Lower infrastructure installation costs benefit 

from PFC “clean input” rectifier (without 

filters) with a lasting high input power factor 

whatever the operation conditions. It means 

lower input current, in comparison with 

traditional UPS, therefore no need to oversize 

upstream transformers or generator sets. 

• Intelligent built-in battery monitoring system 

interacts with “charging mode” to prolong 

battery lifetime (reduced battery stress 

thanks to a very low ripple current). The 

independent charger permanently isolates 

the batteries from the inverter DC bus in 

normal mode. 

• Designed to match latest IT load 

requirement. 

• Leading power factor load compatible 

without derating

UPS 


800 and 900 kVA 

The voltage you require: whatever the load 

DELPHYS MX ensures your power supply is 

of the utmost quality by using Space Vector 

Modulation (SVM) digital regulation: 

• perfectly sinusoidal output voltage THDV < 2 % 

with linear loads and < 3 % with non-linear 

loads, 

• output voltage precision even when load is 

completely unbalanced between phases, 

• an immediate response to major variations 

in load, without deviating the output voltage 

(± 2% in less than 5 ms), 

• a very high short circuit capacity up to 4 In 

(Ph / N) allows selectivity. 

Components and power bridges (integrating 

the latest high performance IGBT) enable 

the supply: 

• non-linear loads with high crest factor up to 3, 

• loads with a leading power factor up to 

0.9 lagging without de-rating of the active 

power (900 kVA / 800 kW).

Integration into your electrical network: a “clean” and economical rectifier 

DELPHYS MX, guarantees total compatibility 

with your low voltage electrical power supply 

system and, in particular, with generating sets: 

• sinusoidal current at rectifier THDI input: 

5 % without filter, 

• increased power factor upstream of the 

rectifier: 0.94 without filter, reducing the 

current consumed, and therefore the size 

of cables and protective devices, 

• gradual, sequential start-up of the rectifiers 

in parallel, facilitating take up by the 

generating set, 

• delayed battery recharge when running 

on generating set to reduce power 

consumption.

Fault tolerant architecture 

DELPHYS MX integrates internal redundancy 

that ensures permanent power supply even 

during system failure: 

• redundant ventilation system, 

• ring bus synchronisation, 

• no single point of failure since the 

synchronisation bus uses a fault tolerant 

token ring topology that accepts an 

accidental opening of the synchronisation 

loop, without UPS malfunctioning or load 

losses and an alarm is given to the operator 

at the first fault. 

• “Cascade failure” protection function 

eliminates fault propagation downstream 

of a module in parallel system when 

configured with central bypass, 

• internal or external “backfeed” protection 

eliminates any risk of energy feedback 

upstream of the UPS, 

• hardware and software watchdog ensures 

that the power supplied to applications 

is secure in case of a circuit and control 

software fault, 

• redundancy of the power supplied to the 

electronics, locating ventilation faults, 

preventative detection of faults on a battery 

component on request. 

SYDIV 030 A 

Protecting your battery investment 

EBS (Expert Battery System) technology 

significantly prolongs the battery life: 

• charge according to an algorithm which 

adapts to the environment and the 

condition of the battery, 

• eliminates overloading effects due to 

permanent floating, which accelerates the 

corrosion of the positive plates and causes 

the separators to dry out, 

• isolation of the DC battery bus, (independent 

charger function). Premature ageing, 

caused by residual ripple from the inverter 

bridge is eliminated. 

Guaranteed battery availability 

• the battery and DC circuit are regularly 

tested automatically and the operator is 

notified of their condition, 

• optional BHC (Battery Health Check) 

function tests analyse the following 

parameters: current supplied by branch 

and voltage of each segment or each block. 

In the event of a problem, the function 

automatically takes corrective measures. If 

the problem continues, an alarm showing 

the location of the fault (branch, segment 

or block) allows maintenance to be easily 

organised.
