Product Overview
The DCM3366Q is a flexible-hose type DC electronic energy meter designed for EV charging, solar energy, and energy storage systems (ESS). It delivers Class 1.0 accuracy for DC energy metering, alongside comprehensive measurement of voltage, current, power, and multi-tariff functions. The device supports direct measurement up to 1000VDC using an external shunt resistor. For data communication, it features an RS485 interface with dual DL/T 645-2007 and Modbus protocol support, as well as an infrared interface for automated meter reading.
Main Functions
Measures voltage, current, and power;
Accumulated electricity consumption over the past 12 months;
Features automatic calendar, timer, and leap year switching functions. The broadcast clock error must not exceed 5 minutes. Do not calibrate the time between 23:50 and 00:10. Only one calibration is allowed per day.
Two tariff periods can be automatically switched according to preset times. At least two time zones can be set for each tariff period per year, with at least eight settings within 24 hours. The minimum time interval is 15 minutes, and time can be set across midnight. Records the last 10 programming and timing operations.
Modulated infrared communication port and RS485 communication port, using DL/T645-2007 communication protocol and Modbus (RTU format) protocol. RS485 communication speed can be set to 1200 bps, 2400 bps, 4800 bps, 9600 bps, or 19200 bps. The modulated infrared communication rate is fixed at 1200 bits per second.
