EM series include AC meter and DC meter. There are 2 models of DC Din rail meter : EM613001 & EM613002. Generally AC energy meters are used for measuring alter-current while DC meter are used to measure direct current. It's worth to highlight that RS485 & NB-IOT communication are optional. EM613001 is a DC metering device Rs485 DC energy meter sampling by shunt with high accuracy. EM613002 is wireless rs485 din rail dc meter with nb-iot communication. They are widely used in New Energy Field- PV, Solar Power/EV charger; Telecommunication Based Station; Energy Management /Battery Storage System; Power Generation System.
1.Brief introduction
EM series include AC meter and DC meter. There are 2 models of DC Din rail meter: EM613001 & EM613002. Generally, AC energy meters are used for measuring alter-current while DC meter are used to measure direct current. It's worth highlighting that RS485 & NB-IOT communication are optional. EM613001 is a DC metering device Rs485 DC energy meter sampling by shunt with high accuracy. EM613002 is a wireless rs485 din rail dc meter with nb-iot communication. They are widely used in New Energy Fields- PV, Solar Power/EV charger; Telecommunication Based Station; Energy Management /Battery Storage System; Power Generation System. Compared with other smart modules, the advantages of this module are as the following:
DC metering device sampling by shunt
Specially designed for EV Charger(fast charging, slow charing, rapid, ultra-rapid)
This DC din rail meter supports RS485 communication, through RS485 and concentrator (EM613002, one NB concentrator can connect 25 RS485 DC meters) to communicate and upload data to the system platform.
We have 2 models of DC Din rail meter : EM613001 & EM613002.Generally, AC energy meters are used for measuring alter-current while DC meter are used to measure direct current. It’s worth highlighting that RS485 & NB-IOT communication are optional. As an RS485 DC Meter, this meter can be applied to New Energy Area, like Solar Systems and EV chargers (Electric cars).
2. Function
Rate: Four Tariffs with 8 Time Slots
Alarm function: over-voltage, over-current alarm, threshold can be set.
Event log: The device itself stores the last 20 records when overvoltage, undervoltage, and overcurrent occur
Display: LCD displays DC power, current, voltage, tariff power, data wheel display (time interval 5S), you can also turn pages by pressing an external button.
Backlight: Press the page turning button to light up the backlight, which is convenient for viewing data when the light is insufficient
Communication: Supports RS485 communication with protocol DTL645, which allows parameters setting and read or write power data
