ABSTRACT:
A watt-hour counter for supplying electrical energy at a remote location from an external power source having a housing with a connection to an external source of electrical power, at least one electrical output mounted externally in the housing and a current measuring means serially connected between the external power source and the electrical output, for producing an output potential proportional to the current at the electrical output. A rechargeable coulometer is coupled to the output of the current measuring means, so that the current sensing means removes a predetermined magnitude of charge from the coulometer proportional to the ampere-seconds used in the external power lines. There is also a charging circuit coupled to the coulometer for charging the coulometer with a predetermined charge, and a switch means serially connected between the external power source and the output, and coupled to the coulometer for interrupting the power to the output in response to a change in potential of the coulometer.
