Liebert Npower ™
Liebert Npower is the next generation of large-scale
UPS, utilizing true double-conversion on-line
technology to protect against the full spectrum of
input and output power disturbances. Liebert
Npower’s all-digital ActiveStar ™ controls are DSP-
based and feature a unique, patent-pending
technology that allows it to make ultra-fast
adjustments to changing loads, including subcycle
pulse-width corrections to keep the output voltage
waveform nearly flawless. The Liebert Npower
system is available in seven models ranging from 30
kVA up to 130 kVA.
The Liebert Npower is rugged enough to handle load
branch faults, input faults, 100% step loads, PDU
startup inrush and motor-load startup. Output
voltage distortion (THD) typically measures less than
2.5%—even under worst-case conditions. The
combination of rugged inverter and continuous-
rated static switch gives the Liebert Npower
exceptional overload capability.
