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 DSPbased 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.
