Watt/Watt-Hour, Var/Watt-Hour Transducers

Watt/Watt-Hour and Var/Watt-Hour transducers manufactured by Ohio Semitronics measure Watt/Watt-Hours, Var-Hours, Watt-Hours, and supply an analog, pulse, or serial output. Watt/Watt-Hour, Watt-Hour, and Var-Hour transducers are typically used in applications where billing for the amount of energy consumed is needed or appliance testing.
