Staco Energy Products Co.
Double Conversion
The UPS provides clean AC power with
voltage and frequency independent
from the utility. On-line technology com-
pletely regenerates utility power
to correct electrical disturbances in the
mains.
High-Eciency 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 40-70Hz and 55-150Vac (for 120Vac
input), or 110-300Vac (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 eciency with low current harmonic
pollution to the utility.
To protect the unit from overloading, the
UPS will automatically switch to by-
pass 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

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 exibility for easy remote control and
monitoring.
Features
DC-start function ensures the start-up of
UPS even during power outages.
Programmable receptacles oer 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.
Emergency shutdown control through
EPO allows users to shutdown the UPS
completely in an emergency to ensure a
safe operating environment.
On-Line, Single Phase
UPS System
The Staco V represents the latest in single-phase
technology at an aordable price. Its true on-line
performance provides a constant clean, steady sine wave
safeguarding the most sensitive equipment.
