DC energy meter
There are 2 models of the DC energy meter: DCEM and E1-3P. Both of the dc kwh meters are designed for measuring and monitoring DC systems. This dc smart meter can measure important DC parameters: Voltage, current, power, and energy, etc. All data in the dc meter are accessible via RS485 using Modbus RTU. Input voltage range up to 1000VDC, and are din rail installing.
DCEM series DC energy meter, including DCEM and DCEM-2, can measure 0-500A and 0-1000VDC. Current inputs are flexible with a Hall CT or a shunt. DCEM is 4 channels metering and hall CT connected. DCEM-2 are 2 channels metering and shunt connected.
E1-3P series DC energy meter can have 1-way independent shunt access or 2-way independent shunt access.
Blue Jay DC energy meter is designed for scenarios such as electric power, communication, railway, transportation, environmental protection, petrochemical, steel, and other industries.
