Chapter 1 Product Introduction
Liebert NXC UPS (UPS for short) is an intelligent online UPS system with sine wave output developed by Emerson Network
Power. The UPS offers reliable and high quality AC power to the precision instrument.
The UPS is applicable to supplying AC power to small scale computer centre, network, communication system, automatic
control 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. The system wiring must be checked
and the panel setting must be conducted 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 life
 Operation and display panel with both LCD and LED indication to help you learn about the system operation state and
operating parameters
 Capable of ECO power supply mode, which helps you save energy to the maximum extent
 Flexible network management with Emerson monitoring software
 Fan fault self-test and automatic recognition functions
 SNMP card optional, providing network communication function
 Capable of connecting multiple battery strings, extending the power supply time of battery mode
