3. Introduction
3.1 System and model description
This Online Series is an uninterruptible power supply incorporating
double-conversion technology. It provides perfect protection
specifically for computer equipment, communication systems to
computerized instruments.
Its true online double-conversion design eliminates all mains power
disturbances. A rectifier converts the alternating current from the
utility power to direct current. This direct current powers the inverter.
On the basis of this DC voltage, the inverter generates a pure
sinusoidal AC voltage, which is constantly powering the loads.
Computers and Peripherals are thus powered entirely by the UPS. In
the event of power failure, the maintenance-free batteries power the
inverter.
This manual is applicable to the tower 3/1 10k-20K models and tower
3/1 10K-31C model.
The tower 3-phase series UPS providing outstanding performance
and reliability, the UPS’s unique benefits include:
l
Online UPS design with pure sine wave output.
l
True online double-conversion technology with high power density,
utility frequency independence, and generator compatibility.
l
Overall high efficiency > 93%, saving the operating cost.
l
True three-phase power factor correction and high input power
factor (PF>0.99). Save the installation cost and reduce the
pollution back feed into upstream power system.
