Abstract
An apparatus supplies AC power to a load. The apparatus includes a set output terminals, a primary circuit, and a load sensing circuit. The primary circuit is electrically coupled to a source of AC power and to the output terminals for selectively providing power at a low voltage at the output terminals or electronically coupling the source of AC power directly to the output terminals. The load sensing circuit coupled to the primary circuit and the source of AC power for determining a resistance associated with the load at initial application of the load and controlling the primary circuit to electronically couple the source of AC power directly to the output terminals if a proper load is detected.
Claims18
An apparatus for supplying power to a load, comprising:
- a pair of output terminals;
- a primary circuit electrically coupled to a source of power and to the output terminals for selectively providing power to the output terminals, the primary circuit for providing power at the low voltage at the application of the load, the primary circuit including a sensor for detecting application of the load;
- and,
- a load sensing circuit coupled to the primary circuit and the source of power for determining a resistance associated with the load at initial application of the load and controlling the primary circuit to electronically couple the source of power directly to the output terminals if a proper load is detected, the load sensing circuit for sensing application of a proper load or an improper load at application of the load.
