DCM230 DC Energy Meter for Solar Panels

DCM230 DC Energy Meter for Solar Panels, the single load din rail DC energy meter, supports 5-1000V DC voltage, RS485 Modbus/ DLT645 communication, were designed for DC energy systems. It can measure multi-parameters like current, voltage, power, frequency, import and export energy, and so on in the DC energy system. Besides a pulse output interface, an RS485 port was provided for  Modbus RTU or DLT-645 protocol. The DCM230 meter has two versions working with AC or DC power supply.
