Battery Management Systems (BMS) plays a critical role in most new energy storage technology. The battery energy storage is direct current, and the dc meter is to measure the storage or consumption of the direct current, and it is generally placed at the output of the energy storage battery. In order to ensure the good operation of the battery management system, dc meter is esstential, dc meters can measure and monitor all important dc parameters: voltage, current, power and energy, etc.
EM series include AC meter and DC meter. 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.
