OFF-LINE UPS SYSTEMS

SB 500

The heart of UPS is a solid state inverter system (PWM) which draws D.C. current from a Battery Bank and gives voltage and frequency regulated AC power that is free from all sorts of power problems. Built in Battery Charger keeps the battery floating in charged condition (when the mains supply is available) and gives about 1/2 hour backup during power failure.
