SMPS Power Supply cum Battery Charger ( OR Float Charger )

SMPS Power Supply Battery Charger

ESI “SMPS Power Supply cum Battery Charger” is meant for feeding load as well as charge the connected battery to provide continuous supply to the load.

AC supply is converted to constant voltage DC by high speed switching and connected to the critical load. Battery of appropriate rating is also connected across the load (or floats across the load) so that during power outage battery feeds the load without any interruption. It may be called a DC UPS.
