On-line, Single-phase
Parallel Redundant UPS System
High Input Power Factor
and Low Current THD
The UniStar ® P meets today’s industry
standard for energy savings and low
refl ected harmonics, and achieves
up to 0.99 Power Factor as well as
<5% THD.
Energy Effi cient UPS
The AC to AC effi ciency of the UPS
may reach up to 91% at 25% load, and
better with larger loads and normal
VFI operation. Using the ECO mode,
up to 98% effi ciency can be achieved.
Smart ECO Mode
In ECO operation mode, the UniStar ®
P normally supplies power to load
via bypass utility. It will automatically
transfer to inverter supply with
SmartECO Mode if the bypass utility
becomes out of tolerance.
Programmable Frequency
Converter
Using the front panel keypad, you
may reprogram the UniStar ® P to
act as a frequency converter for
either 50 Hz or 60 Hz. (Consult factory
for further information)
EPO Function
The Emergency Power Off Function
enables user shutdown of the UPS in
an emergency situation.
Manual Maintenance Bypass
The internal manual bypass ensures
a continuous supply of power to the
critical load during service or periodic
maintenance of the UPS system. The
bypass switch is electrically interlocked
with the inverter to provide safe
operation.
LCD/LED Mimic Panel
A concise LCD/LED display provides
real-time status and readings such
as operation modes, AC voltage,
frequency, battery voltage, load level,
inner temperature, and more. A full-
size microprocessor-based graphical
LCD display provides advanced
monitoring functions.
Intelligent Self-Diagnostics
The DSP self-diagnostics assists the
service engineer in pinpointing system
fauIts rapidly, making repairs fast
and easy.
Silent Fan Control
The UniStar ® P employs forced air
cooling by internally mounted fans
with speed control that is based on
load percentage. This means low
audible noise levels, suitable for most
environments.
