DCEM4 OEM Factory Smart Solar Energy Multi Function DC Power Meter
Description
BJ-DCEM meter is an advanced solution for multi-channel energy metering in DC system. It can visually display voltage, current, power data and energy cumulative data. With a panel keypad, it can set voltage display parameters and the hall CT parameters.
Furthermore, with RS485 communication interface, BJ-DCEM can be connected to the monitoring center. It is a high-performance automatic meter suitable for industrial and mining enterprises, civil construction, building automation. And also these series can measure the power parameters in power grid.
Features
