  • MOSFET based power stage, with PWM AC output.
  • Mains to Backup mode changeover time less than 9mSec.
  • Backup mode protected against Overload, short circuit, reverse phase and unbalanced MOSFET drive.
  • Line Synchronized change over from Mains to Backup and Back.
  • Over current of MOSFET’s protected within micro seconds.
  • Three step AVR with input range 140V to 280V AC. and output range 200-245V AC.
  • MOSFET based PWM battery charger.
  • Automatic low battery warning and cut off.
  • Maximum output load = 600VA Test Points & Observations:
