DCEM Multi-channel DC Energy Meter

DCEM Multi-channel DC Energy Meter

DCEM Multi-channel DC Energy Meter is a DCEM multi-channel DC power measurement terminal device used for measuring DC system electrical parameters. It can visually display voltage current power data and energy cumulative data. Optional shunt or Hall CT connected. Max 4 channels metering is available.

The front panel keypad can be free configuration parameters and the sensor ratio to expand measurement range. With the RS-485 interface, the MODBUS-RTU protocol can be connected to the monitoring center. This DCEM DC Energy Meter is a high-performance automatic meter suitable for UPS systems to detect Solar energy plants monitor industrial and mining enterprises, civil construction building automation, etc.
