DCEM are special design for DC circuit metering, muti-channels signal design can much reduced the hardware cost of project. One meter provide different four channel amp reading and energy consumption value record. same 35mm din rail mounting shell can work with Blue Jay MCM series meter for combine energy metering project in AC & DC circuit. Optional analog, digital, relay and alarm output is available via field-swappable plug-in communications modules. Also provide on-board RS485 serial communication port (MODBUS RTU) to send data to the external systems. ·DC Excitation Systems ·Light Rail Transit Systems ·EV Charging Monitoring ·Data Center ·Cellular Tower Energy Monitoring ·DC Energy Management Systems ·Power Distribution for Telecommunication Room ·Solar Photovoltaic Systems ·Industrial DC Control Systems ·Metallurgy and Electroplating Industries ·Wind Power Generation Features: ·DC power / energy sub-meter provides Voltage, Current, Power and Energy measurements ·Monitor and control power switches ·Bi-directional for renewable systems (NET metering) ·Interfaces with shunt or external Hall Effect current sensors ·Up to 1000Vdc Voltage input ·Up to 4 channels energy metering ·Record last 30days energy data for all channels ·RS-485 connectivity - Modbus RTU ·Optional alarming and analog output ·Optional 4 channels digital inputs / 2 channels digital outputs
