BATTERY BACK-UPS FOR PELLET STOVES
Battery Back Up
For Alternative Heating Appliances
750 Watt Capacity
SF 503A interfaces between a heating appliance (wood pellet or alternative fuel stove) and its AC wall outlet. When AC utility power is present, the SF 503A charges a battery and monitors the wall outlet to detect a power outage. At the moment utility power fails, the SF 503A draws energy from a battery and converts it to enable appliance operation. When utility power returns, the SF 503A automatically switches the appliance back to AC wall outlet power. At the same time, the SF 503A resumes charging the battery to return it to full capacity in preparation for the next power failure.
