Emerson Power Solutions manual Standard And Optional Features Of The Liebert Npower UPS

Liebert Npower™

Innovative power protection for maximum power quality.

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.
