3 Phase Kilowatt Hour Meter
Semiconductor technology issued to produce a very compact electronic kWh meter as a replacement for electro-mechanical check meters. The meter is a three element device with three CT inputs giving true readings on 4 wire unbalanced systems. In addition to the integral 7 digit counter there is an NPN open collector pulse output for use with dataloggers or similar electronic recorders or controllers. The compact circuitry employed allows this meter to be housed in a standard 4M wide Din rail mounting case.
