Product Details
There are 5 models of DC meter: EM613001/EM613002/EM619001/EM619002/EM613005. It's worth to highlight that RS485 & NB-IOT communication are optional. EM series DC energy meters are designed for measuring and monitoring in DC systems. 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. The meter working with DC power supply. Input voltage range up to 1000VDC, and current inputs are flexible with DC shunt. The multi-tariff version has a RTC equipped inside, it can provides multi-tariff information and monthly records.
EM619001 is a 5~1000VDC/0~2000A dc meter 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. It is suitable for DC energy metering of EV charging piles, battery storage, base station, solar panels and other devices with DC signals.

Wiring and Dimension
Measurement: Using shunt sampling, high measurement accuracy; can measure DC power, current, voltage and other parameters
Alarm function: Overcurrent alarm. When the current exceeds the CT1 value set by the meter, an alarm will occur. The meter LCD will display the alarm sign. At the same time, the LCD supports RS485 communication: used for parameter setting and data reading; DTL645 protocol and Modbus Protocol compatible
The DC backlight is bright red (overcurrent alarm LCD displays Code 01, overcurrent threshold 250A)
Display: LCD backlight display, supports various parameter displays, power data and instantaneous parameters.
Single-phase auxiliary relay for over-current cut-off signal output (can control external relay to cut off the line)
Firmware upgrade: supports RS485 local upgrade
