Three Phase Input Three Phase Output

The HF Series includes the 10KVA to 250KVA (3 phase input, 3 phase output) double conversion On-Line UPS with an isolation transformer. The Load is supplied continuously by the inverter with clean, stabilized and regulated sine wave output power.

Input & Output filters protect the load from Voltage fluctuation and surges. Its applications include mission critical load like IT, Call Centres, Hospitals, CNC machines etc. Thanks to state-of-the-art microprocessor based high frequency PWM technology.
