Product Overview
The DCM3366D is purpose-built for DC metering. It measures DC voltage and DC current (via external shunt), then computes DC power and cumulative energy metrics. With support for forward, reverse, and net energy modes, it is perfect for systems requiring both consumption and feed-back tracking (for example, battery discharge/charge cycles, solar export). The meter is CE and UKCA certified, ensuring compliance with key markets in Europe and the UK.
Equipped with an LCD interface, the device offers quick visual readouts. With RS-485 (Modbus RTU) communication, it can seamlessly integrate into BMS / EMS / SCADA systems. Its rugged design, surge immunity, and data retention capabilities ensure reliability in the field.

FAQ (Sample Questions)
Q: What makes this meter CE & UKCA certified?
A: It meets the regulatory safety, EMC and measurement directives required to export to EU and UK markets.
Q: Can it measure energy both ways?
A: Yes, it supports forward, reverse, and net energy modes — perfect for systems with energy feedback (e.g. battery, PV export).
Q: What communication protocol is supported?
A: RS-485 with Modbus RTU is supported by default; custom protocol support may be available.
Q: What is the operating temperature range?
A: (Replace with your spec) e.g. –25 °C to +60 °C — you should refer to actual model sheet.
Q: Do you provide calibration certificates or test reports?
A: Yes — we can arrange calibration and certification documentation per request, especially for tenders.
