25KVA Three Phase Inverter Type MIN 253U

APPLICATION :
Converts 110VDC power from batteries to 415VAC, 3phase, 50Hz power, for supply to Compressor and Fan Motors of Air Conditioners, in Air Conditioned Railway Coaches. The equipment is designed for underslung mounting below the coach.

OPERATING PRINCIPLE :
The Input DC Voltage is boosted to higher Voltage levels suitable for particular operating Voltage. The boosted voltage is fed to a 3Phase PWM Sine-wave Inverter to get three phase Output. The three phase output is passed through harmonics filter. The output is protected against short circuits and overloads.
