WATTHOUR, WATT & WATTHOUR TRANSDUCER

The watthour is the number of watts used in an hour. A 60 watt light bulb left on for 1 hour would use 60 watt-hour of energy. Watthours is the engineering units utilities use to bill commercial customers. DAE JOO's Watthour Transducer have a built-in Linear integrator circuit. This circuit accepts signals from watt portions and integrates it with respect to time. This produces a pulsed output via volt free (only Relay output) contracts, resulting in pulse proportional to kilo watt-hour.
