Product parameters

Product Details

  • 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. Compare 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 din rail DC meter support 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.
