More Information

High efficiency


98% in Ecomode

93% in normal mode double conversion



Il can works in parallel up to 8 unitsto reach the highest power of 6400kVA

Optimal protection system


Remote shutdown in case of emergency, backfeed protection

Uninterruptible power supply for data center and heavy loads

It is the maximum electrical protection combined with a particular strength and a structural flexibility for different applications.

The inverter has an integrated isolation transformer and the rectifier with IGBT technology allows very low current harmonic distortions to the network. Rectifier is available also with SCR (6 or 12 pulses) and with optional selective filters to reduce harmonic distortions. The digital control has DSP (Digital Signal Processor).

It is available in the single phase range from 10kVA to 100kVA, in the three phase range from 10kVA to 800 kVA and in parallel with 8 units up to 6400 kVA.
