1. Brief introduction
EM series include AC meter and DC meter. There are 2 models of DC Din rail meter : EM613001 & EM613002. they can be used for dc system remote monitoring.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. As a NB-IOT DC Energy Meter, this meter can be applied to New Energy Area, like Solar System and EV Charger (Electric Car). It can also be used as a DCU with multiple EM613001 to serve as a sub-metering system.
