Product Details
Solar PV panels are a growing source of renewable energy which involves DC electricity production. The need to monitor these systems, providing accurate energy measurement before conversion to AC is crucial for reflecting true efficiency and conversion losses. The DC charging station has an integrated converter that transforms the alternating current from the mains into direct current. This allows the electricity to be fed directly into the vehicle's battery.
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.
EM613001 is a DC metering device Rs485 DC energy meter sampling by shunt with high accuracy. EM series dc meter is designed for scenarios such as DC panel, battery storage system, charging pile and telecom base stations. This meter can measure voltage, current, power and active energy in DC system. It be used as local display and used in measuring system.
