MCM2401 Din rail AC electrical multi-channel power meter, 3 phase electric electric meter
Description
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.
MCM 2401 is used for 12 channels 1P2W single phase branch circuit electrical parameter collection. This product is installed with standard din-rail and is 6 models (1 model is 17.5mm) in width. In addition, with 1.6'' dot matrix LCD interface, MCM2401 can easily display all parameters on the screen.
Because of its 0.5 class high-precision performance, the product can replace multiple digital energy meters. Moreover, MCM 2401 can reduce equipment investment in electrical metering projects, improve equipment reliability and reduce maintenance costs.
