system and precision instrument.
This chapter introduces the features, model configurations, appearance and components, operating principle, UPS
state and operation mode, and specifications of the UPS.
1.1 Features
The UPS features include:
 Compatible with two modes: 3-phase mains output and single-phase mains output. You should check the
system wiring and conduct the panel setting manually
 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 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
 Intelligent battery management to extend the battery module life
 Operation and display panel with both LCD and LED indication to help you learn about the UPS operation state
and operating parameters
