TSi Power’s Outdoor VRp-ILc automatic
precision voltage regulator with built-in
low-impedance isolation transformer
allows trouble-free operation of electronic
equipment over a very wide mains ac
voltage range of 400V+/-20% found in
many developing countries.
There is no switching of taps nor any break
in the power path thanks to continuous
pulse width modulation (PWM) switching of
a buck-boost transformer primary winding.
Typical applications
Designed for applications where absolutely
safe and precisely regulated ac power is
required, such as radio base stations (RBS),
telecommunication transmission sites for
backhaul (including microwave links), TV/
radio broadcasting, industrial equipment and
end-of-line utility equipment.

Key Outdoor VRp-ILc features
• Outstanding voltage regulation
performance:
output is within 230/400vac+/-3%
under a normal input range
of 400vac +/-20%
• No switching of power path and
unit always starts up on sine wave
zero crossing
• Over-voltage cutoff, with automatic
restart when ac mains voltage
returns to normal (safe) condition
• Failsafe: automatic bypass (even
during bypass, the over-voltage
protection is active)
• Lightweight design
VRp-ILc
provides
continuous,
fast, no-break
voltage regulation
• A three phase low-impedance
isolation transformer is used
for maximum reliability
• Coordinated surge protection
per IEC61312
• Advanced noise and interference
filter reduces dV/dt from
6kV/µs to less than 10V/µs
• Pedestal-mountable cabinet

Key Outdoor VRp-ILc benefits
The lightweight, high efficiency Outdoor VRp-ILc is easy to install in outdoor
environments. The unit comes in a specially designed outdoor rated enclosure
with multiple air exhaust fans. To maximize cooling, the isolation transformer is
housed in an IP23 outer enclosure. Sensitive components are housed in an IP55
inner case. Overall equivalent is to an IP44(NEMA-3R) enclosure.
The automatic bypass assures that connected equipment will not shut down,
even if VRp-ILc fails. VRp-ILc is compatible with all loads as it does not switch
any components in the power path. VRp-ILc’s ultra-low impedance assures
stability even with the most demanding loads.
The automatic over-voltage cutoff with automatic restart ensures that operation
is off-line during serious over-voltage situations that could damage the system
and/or load, and then restarts without intervention when the ac mains voltage
returns to the normal operating range.
The ILc isolation line conditioner components provide maximum equipment
protection against surges, spikes and transients, for higher equipment reliability
and maximum equipment operating life. In addition, the VRp-ILc offers
improved repeatability, fewer reboots or system lock-ups. A reduction in
equipment down time and service costs can also be expected.
How the Outdoor VRp-ILc works
The high frequency insulated gate bi-polar transistor (IGBT) driven converter
takes the incoming ac power, measures against the nominal voltage and adds
or subtracts voltage, 20,000 times per second, to achieve precisely regulated
230/400 vac three phase output.
The Automatic Bypass will be activated when there is a fault condition.
A green LED indicates normal regulated protected mode operation.
The over-voltage cutoff is activated whenever the ac mains voltage becomes
dangerously high (over 475vac). It automatically restarts whenever ac mains
voltage is restored to a safe level.
At extremely low ac input conditions it can be operated at limited duty cycle.
A low-impedance isolation transformer provides complete isolation between the
primary and secondary, and permits bonding between output neutral to ground,
which completely eliminates all disturbances between neutral and ground.
The leakage inductance of the isolation transformer, in combination with
capacitive elements and metal oxide varistors (MOVs), provide superb noise
filtering, as well as coordinated multi-stage surge protection in accordance with
the principles of IEC-61312. Multiple cooling fans control the unit’s internal
temperature, with intakes at the bottom of the unit and exhaust through the top
rear of the unit, protected with a rain guard/sunshield.
