DCPM Multi-channels Isolated DC Circuit Monitor

DCPM Multi-channels Isolated DC Circuit Monitor

DCPM Multi-channels Isolated DC Circuit Monitor, a new design din-rail mounting DC metering device, provides standard 8 channels, max 24 channels isolated measurement, and collects DC circuit basic parameter value (Volt, Amp, Power, Energy consumption & generate), This dc voltage monitor uses RS485 MODBUS line sends data to site server or remote SCADA.

The DCPM Circuit Monitor is an extremely low data refresh interval (20ms per cycle), suited for field devices’ power circuit condition monitoring such as Solar plant and Telecom server room, BMS applications in UPS systems, etc.
