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 suitable for DC energy metering of EV charging piles, battery, telecom tower, solar panels and other devices with DC signals. It is also suitable for DC power distribution electricity system of mining industry, civil buildings, building automation system base and so on.
