Double Conversion
The UPS provides clean AC power with
voltage and frequency independent
from the utility. On-line technology
completely regenerates utility power
to correct electrical disturbances in
the mains.
High-effi
ciency and protection
PWM sine-wave topology yields
excellent overall performance. The high
crest factor of the inverter handles all
high in-rush current loads without the
need to upgrade the power rating.
Wide frequency and voltage windows
of 45Hz - 65Hz and 60-144Vac (for
120Vac input), or 120-288Vac (for
230Vac input), are provided, which
help to extend the life of the battery.
Near unity input power factor meets
today’s industry standard for energy
savings and effi
ciency with low current
harmonic pollution to the utility.
To protect the unit from overloading,
the UPS will automatically switch to
bypass mode in 30 seconds if loading
is at 105%~120% of rated capacity.

It will automatically switch back
to inverter mode once overload
condition ceases. Selectable bypass
input voltage tolerance (low/high
sensitivity) prevents under or over
voltage being supplied to the loads,
while in bypass mode.
User Controls
An easy-to-read user friendly LCD
display provides real-time indication
of all major system parameters and
status, including load level, battery
remaining and fault signals, for easy
service.
Digital signal processing (DSP) also
provides the UPS with powerful com-
munication capability, which enhances
the fl exibility for easy remote control
and monitoring.
Features
DC-start function ensures the start-
up of UPS even during power outages.
Programmable receptacles off er
the capability to load shed during any
power interruption, while in battery
power mode or during overload
condition, via the use of special
communication software provided,
thus reserving backup power for
priority loads.
