AC energy meters for charging infrastructure

At charging currents of up to 40A (single-phase) or of up to 80A (three-phase), the energy data can be used directly for billing purposes, even without an additional current transformer. The devices measure in accordance with EN 50470-3 accuracy class B, which normally means a measurement deviation of a maximum of one percent. At lower temperature requirements of up to +55 C, the EEM-EM357 EMpro energy meter, which satisfies all e-mobility requirements, can continue to be used.

All energy meters of the EMpro product family record the energy values fully bi-directionally in all four quadrants and are certified in accordance with the MID. The data is forwarded to the charging controller and from there to the backend provider via the integrated Modbus/RTU interface. Other versions with Modbus/TCP and M-Bus interfaces are also available.
