Product Overview
The DCM3366-4-W1 is designed specifically for DC applications. It measures DC voltage and DC current through external shunts, calculates DC power and accumulated energy, and supports forward/reverse/net energy modes — essential for bidirectional systems such as vehicle-to-grid (V2G), battery charge/discharge monitoring and PV+ESS installations.
With a readable LCD interface, robust surge and ESD protection, and standard RS-485 communications, the DCM3366-4-W1 is built for reliable field operation and seamless integration into energy management and telemetry systems.
