Din Rail Energy Meter
(Din Rail Watt Hour Meter, Three Phase Din Rail KWH Meter)

DT(S)S238-7 ZN
DT(S)S238-7 RS485 Din Rail Energy Meter

DTS238-7 ZN three phase four wire or DSS238-7 ZN two phase three wire energy meter is designed to mount on the 35mm Din rail for easy installation. Being only 7 module width, it supports RS485 communication port as well as infrared port. There is no need for external CT since this product uses direct wire connection. Our products are capable of measuring the active energy, reactive energy, real current, real voltage, real power, power factor of AC power grid. In addition, this product uses four tariffs for different amounts of demand.
