MCM1000 Single Phase Smart Meter Multi Channels ac energy meter Multi Circuit Monitoring
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.
MCM1000 series provide a compact and robust metering solution, enable reliable monitoring of building electrical loads with a low installation cost-per-point by combining sub-metering. The unit performs real-time metering, measures energy consumption for max 18 channel circuits for single phase or 6 channel for three phase circuits.
