Product Overview
Designed to work in EV chargers, solar systems, and energy storage systems (ESS), the DCM3366D series meter measures DC voltage, current, power, and energy with high accuracy and supports forward / reverse energy measurement. It adopts LCD for clear readouts and uses RS-485 communication protocols (Modbus RTU or DL/T 645) to integrate with monitoring platforms, giving you full visibility and control.
The meter supports a wide range of DC inputs (e.g. DC100 V, 300 V, 500 V, up to 1000 V) and works with external shunts for high-current measurement. It is designed for industrial-grade reliability, data retention, and multiple tariff support.
