Product Description

The DCEM-4MS Dual-channel DC energy meter is a highly integrated product for measuring DC parameters. When used with a shunt or external Hall sensor, it can accurately measure 1-2 channels of DC voltages and currents (with direction), power, total electricity, each single-circuit electricity, and other electrical parameters. It can also be equipped with optional DI modules.

DCEM-4MS has RS485 and supports MODBUS-RTU communication the protocol, which can upload the collected allows it toa and equipment status. DCEM-4MS is widely used iItic power, communications, railways, transportation, environmental protection, steel, and other industries to monitor the current and power consumption of DC equipment.
