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 and
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 B500EVO-100-B/B500EVO-200-B
models.
The UPS provides outstanding performance and reliability. The
UPS’s unique benefits
include:
Online UPS design with pure sine wave output.
True online double-conversion technology with high power
density, utility frequency independence, and generator
compatibility.
Overall high efficiency > 93%, saving the operating cost.
True three-phase power factor correction and high input power
factor (PF>0.99). This saves the installation cost and reduce the
pollution back feed into the upstream power system.
High output power factor(0.9), to adapt more type load.
