What it does
- Bidirectional active energy for charge and discharge accounting
- EV DC charging metering per GB/T 29318-2012 non-onboard charger requirement
- Protocol auto-adaptation between Modbus-RTU, DL/T 645-2007 and DL/T 698
- Energy pulse output for revenue-testing or a second data capture device
- Wide temperature range down to -40 C for outdoor cabinets
Before you request a quote
- Maximum and minimum load current (to size the shunt)
- String or bus voltage, and whether energy is bidirectional
- Which protocol your system expects
The meter measures current through an external shunt, so please state the load current together with the voltage. We then confirm the model, shunt rating, torque sequence and register list within one working day.
