For kilowatt-hour-measurement, we build in another Linear integrator Circuit. This circuit accepts signal from Vars portion and integrates with respect to time, to produce a pulse output via volt free contacts, result in pulse proportional to kilowatt hours.
Placed on the rail type with DIN.
Designed according to the dimensions of the German Standards Association DIN 46277.
