DCM3366D series electronic DC energy meter is a new generation product produced by our company. It adopts a liquid crystal display and has an RS485 communication function for data exchange with a microcomputer. It is suitable for power measurement and energy metering of DC signal equipment such as batteries and solar panels. It can also be used in modern supply and distribution DC systems such as industrial and mining enterprises, civil buildings, and building automation.
It is composed of a measurement unit, data processing unit, communication unit, display unit, etc., and has the functions of electric energy measurement, data processing, real-time monitoring, and LCD. The electric energy meter has the characteristics of high overload, high accuracy, low power consumption, automatic saving of power outage data, and long life.
Forward and reverse electric energy measurement, combination = forward + reverse; Voltage, current, power measurement; Electricity settled in the last 12 months; It has calendar, timing and leap year automatic switching functions, and has a time adjustment function. Among them, the clock error of the broadcast time adjustment shall not be greater than 5 minutes. The time adjustment is not allowed within ten minutes before and after zero o’clock, and the time adjustment is only allowed once a day; It has two sets of rate periods, which can be automatically switched through the preset time. Each set of rate periods can have at least 2 time zones throughout the year, and at least 8 time periods can be set within 24 hours, with a minimum interval between periods. is 15 minutes, and the period can be set across zero points; Have the last 10 programming records and the last 10 school time records; Modulated infrared communication interface and RS-485 communication interface adopt DL/T645-2007 communication protocol and Modbus (RTU format) protocol. The communication rate of RS485 can be set at 1200bps, 2400bps, 4800bps, and 9600bps. The communication rate of modulated infrared is fixed at 1200bps.
Rated current (Ib): 50A, 100A, 200A, 300A, 500A, etc. can be set (maximum measured value 4800.0000A), using an external 75mV shunt input Auxiliary power supply: power supply voltage, DC20V～60V or AC85～265V/DC85～330V optional Working temperature range: -25℃～60℃ Dielectric strength: Voltage/power supply/casing: 3.0kV/min Communication/power supply: 3.0kV/min Static electricity immunity: contact discharge 8 kV, gas discharge 15 kV Electrical fast burst immunity: 4kV Surge immunity: 2kV/4kV
