Liebert Power Systems Test Center
Test Capacity and Performance of Liebert Power Solutions
The Liebert Power Test Center for large UPS systems consists of multiple test
stations in each of seven test bays. Testing is customized based on the complexity,
size and number of UPS components in the configuration, but always includes
analysis of every module as well as the entire system. Module and system tests
include:
Steady-state — 0% to 100% plus overload, unbalanced loading; non-linear loading
Dynamic — 0% to 100% step loads plus overload, unbalanced loading; non-linear
loading
Overload and faults — (>100%, 125%, 150%)
Plus other customer-specified special test requirements.
Testing on large Liebert UPS systems, may include UPS power modules, input and
output switchgear, power distribution units, static transfer switches, and battery
cabinets.
Test results certify the input and output, AC and DC characteristics of the system.
Performance comparisons against specifications include, but are not limited to:
Voltage and waveform
Voltage regulation
Voltage and current harmonics
Frequency
Current and waveform
I/O power factor
Efficiency based on kW in and out
System switching, control and monitoring functionality
The Liebert Power Test Center for large
UPS systems is a state-of-the-art test
facility designed to provide customers with
pre-installation testing of the performance,
interoperability, and efficiency of Liebert
power modules and systems under a variety
