Product Overview
The DCM3366Q meter is designed for DC measurement — typical in solar PV strings, DC combiner boxes, or battery systems. It accurately monitors DC voltage, DC current (via external shunt), instantaneous power, and cumulative energy. The unit supports bidirectional energy accounting (forward, reverse, net), enabling energy export / feedback scenarios.
With specifications supporting up to DC1000 V input, rated currents from 50A up to 500A (customizable), and supporting auxiliary power via DC20–60 V or AC85–265 V (or optional DC100–330V), it’s flexible for many DC system architectures. The meter is compliant with Class 0.5 / 1.0 accuracy levels and supports energy display up to 999,999.99 kWh.
Other featuring items include clear LCD blacklight display, RS-485 (Modbus RTU) interface, and robust design for operating temperatures between –25 °C and +60 °C.
