ELECTRONIC POWER GENERATOR
(INVERTER)
`Electrogard' Electronic Power Generator offers freedom from frequent power failures that leave you in complete darkness. It finds application in home lighting (Tube Lights, Fans, Coolers & TV) without any noise, smoke, and oily and greasy environment. Also it saves you from the problem of cranking conventional engine driven generators.

The system operates from a 12V/24V Battery (180AH) that takes over automatically in case of power failure and provides 220VAC supply for your application. It has a built in heavy duty, SCR based Constant Voltage, Constant Current Battery Charger to charge the battery when power resumes.

Salient Features

  • Automatic change over
  • Over load/ Short circuit protection
  • Reverse battery polarity protection
  • Low battery cut-off to prevent deep discharge of battery
  • Controlled output voltage in inverter mode
  • High efficiency MOSFET based inverter
  • Heavy duty SCR based 10 Amp. CVCC charger for extended battery life
