Product Details
EM619001 DC energy meter is designed for measuring and monitoring in DC systems.
The din rail DC energy meter can measure of important DC parameters: Voltage, current, power and energy etc. All data in the meter are accessible via RS485 using Modbus RTU/DTL645. The meter working with DC power supply. Input voltage range up to 1000VDC, and current inputs are flexible with DC shunt, built-in relay for over-current cut-off, over-voltage alarm.
The multi-tariff version has a RTC equipped inside, it can provides multi-tariff information and monthly records.
It supports bi-directional current measurement used in solar PV, ev charger and wind turbine power generation as well as other applications such as transportation systems, communication base station, and data center. It can also be equipped with digital inputs for switch monitoring, relay outputs for remote control, and an over-range alarming.
