Product parameters
Product Details
1.EM series DC energy meters are designed for measuring and monitoring in DC systems.
2.The din rail DC energy meters can measure of important DC parameters: Voltage, current, power and energy etc. It also support bi-directional measurement. All data in the meter are accessible via RS485 using Modbus RTU/DTL645.
3.The meter working with DC power supply. Input voltage range up to 1000VDC, and current inputs are flexible with DC shunt.
4.The multi-tariff version has a RTC equipped inside, it can provides multi-tariff information and monthly records.
5.EM series dc meter is designed for scenarios such as DC panel, battery storage system, charging pile and telecom base stations.
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.
