Electric energy meter for DC applications DC22M

single-phaseDIN railRS-485

DC22M series are designed for direct current energy analysis and energy metering. The products adopt shunt access mode. The current of the shunt supports a maximum of 2000 A. The shunt supports positive and negative connection modes to improve the wiring flexibility of the shunt. This series of meters can measure voltage, current, power and positive and negative charge in the DC system. The DC22M series have RS485 communication interface with highest baudrate 38400bps, supporting Modbus or DLT645 protocol for remote reading. At the same time, the large-screen LCD and touch buttons help users to view and set various measurement parameters on site. Password protection function is added to greatly improve the data security.
