Fluorescent Lights & Power Supplies

Some devices cannot be detected when scanned by Load Sense circuitry. Small fluorescent lights are the most common example. Some computers and sophisticated electronics have power supplies that do not present a load until line voltage is available. When this occurs, each unit waits for the other to begin. To drive these loads, either a small companion load must be used to bring the inverter out of its search mode, or the inverter may be programmed to remain on by defeating the search mode feature.

Clocks

The inverter’s crystal-controlled oscillator keeps the frequency accurate to within a few seconds a day. Most clocks do not draw enough power to trigger the load sensing circuit. In order to operate without other loads present, the load sensing will have to be defeated. The best solution is to buy a battery-operated clock or a clock that is not dependent on line frequency and voltage.

Searching

If the amount of power which a load draws decreases after the load turns on, and if this “on” load is less than the load sensing threshold, it will be turned on and off by the inverter. Incandescent light bulbs may present this problem when the load sensing threshold is set near the wattage rating of the bulb. The solution is to reduce the load sense power threshold.
