MCM400 Din rail AC electrical multi-channel power meter, 3 phase electric electric meter
MCM series multi-channels power meter is a metering device specially designed for feeder loops. The design of multi-function provides electrical parameter measurement for three-phase or single phase branch circuits. Furthermore, MCM series perform real-time metering, measure energy consumption and monitor power quality. There are advanced communication options, including Modbus via RS485, optional Ethernet. Multiple digital input ports can collect pulse signal from water meters and gas meters etc.; and relay output port can remotely control field devices from host server system.
MCM400 series is used for residential / commercial sub-metering, sampling the current signal through an external small open loop transformer. With compact size, the product can be easily installed in the metering box. Moreover, RS485 port is easy to build monitor network, which enables reliable monitoring of building electrical loads with a low installation cost per-point.
