Product Details
1.There are 4 models of DC meter: EM613001/EM613002/EM619001/EM613005. It's worth to highlight that RS485 & NB-IOT communication are optional.
2.EM series DC energy meters are designed for measuring and monitoring in DC systems.
3.The din rail DC energy meters can measure of important DC parameters: Voltage, current, power and energy etc. It also support bi-directional measurement. All data in the meter are accessible via RS485 using Modbus RTU/DTL645.
4.The meter working with DC power supply. Input voltage range up to 1000VDC, and current inputs are flexible with DC shunt.
5.The multi-tariff version has a RTC equipped inside, it can provides multi-tariff information and monthly records.
6.EM series dc meter is designed for scenarios such as DC panel, battery storage system, solar PV system, charging pile and telecom base stations.
EM619001 is used to monitor and control DC system. They also support limit alarm, analog output, digital input, relay output and communication functions. It has the function of energy metering, data processing, real time monitoring and LCD display. It has the advantage of high overload, high accuracy, low power consumption, automatic data save after power failure, long service life and so on.
The meter can have relay alarm output and digital input function; You can set the ratio, alarm, and communication through the meter panel keys according to different requirements. The meter can have event recording of switch (Modbus protocol), programming and event setting records(645 protocol), instantaneous and timing freeze function of data (645 protocol), maximum and minimum value recording function of voltage and current power.
