ITA 5kVA and 6kVA UPS (UPS for short) is an intelligent online UPS system with sine wave output developed
by Emerson Network Power Co., Ltd (Emerson for short). The UPS offers reliable and high quality AC power to the
precision instrument.
The UPS uses modular design, and rack/tower installation can be used depending on your requirements. It is
applicable to supplying AC power to small scale computer center, network, communication system, automatic control
system and precision instrument.
This chapter expands the features, model configuration, appearance, components, operating principle, operation
status, operation mode and specification of the UPS.
1.1 Features
The UPS features include:
Compatible with two mains input modes: 3-phase and single-phase input mode, with automatic input recognition
function
Capable of parallel connection to achieve up to 3 + 1 parallel redundant power
High-frequency double conversion topology structure, with high input power factor, wide input voltage range, and
output immune to power grid interference, thus adaptable to areas with unstable mains supply
High power density
Full digital control technology based on digital signal processor (DSP) to achieve high system reliability with
self-protection and fault diagnosis functions
Excellent intelligent battery management to extend the battery life
Display panel with both LCD and LED indication to help you learn about the UPS operation status and operating
