Product Description
The Model 933 interfaces between a heating appliance (wood pellet or alternative fuel stove) and its AC wall outlet. When AC utility power is present, the Model 933 charges a battery and monitors the wall outlet to detect a power outage. At the moment utility power fails, the Model 933 draws energy from a battery and converts it to enable appliance operation. When utility power returns, the Model 933 automatically switches the appliance back to AC wall outlet power. At the same time, the Model 933 resumes charging the battery to return it to full capacity in preparation for the next power failure.
