What is a DC energy meter?

DC energy meter is designed for DC screen, solar power supply, telecom base station, subway and other applications.

How does a energy meter work?

The DC voltage and the DC current are measured separately with two DMM, and the results are multiplied to get the DC power.

Which signal input does dc energy meter support?

voltage supports 1000V input, current supports shunt (0-75mV), Hall sensor (0-20mA, 4-20mA, 0-5V) access.

How Does DC Power Meter Work?

DC power meter by measuring voltage, current, power, forward and reverse energy in DC systems. It can not only be used for local display, but also can be connected with industrial control equipment and computer to form a measurement and control system. The instrument can have RS-485 communication interface, using Modbus-RTU protocol. Theoretically, up to 128 instruments can be connected on a line at the same time. Each instrument can set its Addr and baud, and also can be selected by setting.
