 UNINTERRUPTED POWER SUPPLY SYSTEM
State-of-the-art
ONLINE UPS with foreign collaboration from "Neel"
Uninterrupted Power Supply is a device which is connected
between main supply & critical load to provide clean, pure
sine wave output without any interruptions during normal
solutions and also during power outages.
Our UPS manufactured under foreign technical collaboration
with Powertech Australia and has advanced PWM technology (IGBT
Based).
NRE POWERTECH UPS is a On-line UPS battery bank on float.
This ensures the change over time is '0' msec and continuity
of power is ensured. Raw power is rectified from AC to DC
and inverted from DC to AC hence the electrical noises are
also isolated to feed load with electrically clean power all
the time. Our UPS manufactured under foreign technical
collaboration with Powertech Australia and has advanced PWM
technology (IGBT Based). Our UPS manufactured under foreign

|
Programmable Battery Low: Advises
level of Battery power available 5%, 25%, 50% or 75%
of total Battery Capacity. This facility enables
early warning of Battery discharge. |
|
|
Auto Start/Stop: Stops Automatically
if an internal fault occurs or battery is
discharged, to protect battery. |
|
|
Failsafe Hybrid By pass switch: For
transfer to mains & vice versa (as standard).
Reverts to inverter automatically when mains return. |
|
|
Separate By pass input Available: In
case of mains & Inverter failure, the load will be
transferred to auxiliary supply, which need not be
mains supply, eg DG Set. |
|
|
Indications: UPS Status & near true
RMS load Indicator. |
|
|
Dimensions: Substantially compact
dimensions with smaller foot print occupying minimum
floor space. |
|
|
Silent operation & aesthetic looks,
can be installed in the office premises, no separate
room / enclosures required. |
