99.4% EFFICIENCY

kVA / kW

HE – High Efficiency
Master HE series is available from 100 to 800 kVA. The UPS feature a new on-line double-conversion technology utilizing IGBT and DSP (Digital Signal Processor) control to provide maximum protection, power quality and green energy for any type of application including primary datacenters, disaster recover sites, telecoms rooms, industrial processes and security applications.
High efficiency stands for higher active power available if compared with legacy UPS thanks to output unitary p.f. Nominal power is granted with no downgrading independently from operating temperature.

Zero impact source
Master HE has a zero impact on connected power sources – grid networks or generators:

≤ 3% input current distortion
Input power factor 0,99
power walk-in function – to ensure a progressive rectifier start-up
start-up delay function – to restart the rectifier when the mains power supply is restored.
