4.FAQ
1. What is the maximum voltage and current range of the EM619002 DC energy meter?
The EM619002 supports DC voltage measurement from 5V to 1000V and current measurement up to 2000A when used with a compatible external shunt. It is designed for high-current DC applications, including EV charging stations, battery energy storage systems, and photovoltaic power systems.
2. How does the EM619002 measure DC current up to 2000A?
The EM619002 uses an external shunt for DC current measurement. The shunt converts the current flowing through the power circuit into a small voltage signal, which the meter measures to calculate current and energy consumption.
The shunt must be selected according to the actual current range and rated output signal. Correct shunt matching and installation are essential for accurate measurement.
3. Can the EM619002 measure both energy consumption and energy export?
Yes. The EM619002 supports bidirectional DC energy measurement. It can measure energy flowing in both directions, making it suitable for applications where DC power can be supplied to or received from the grid-side converter, battery, or charging system.
This function is particularly useful for bidirectional EV charging, battery energy storage, and photovoltaic systems with DC energy exchange.
4. What measurement parameters can the EM619002 provide?
The EM619002 measures DC voltage, current, and active energy. It supports bidirectional energy measurement and provides RS485 communication for remote data acquisition.
These parameters can be used for DC power monitoring, energy consumption analysis, charging statistics, and integration with compatible energy management systems.
