Benning Wallbox tester

Benning EV 3-3 is a wallbox tester and measurement adapter that allows for easy and quick functional testing as well as troubleshooting of wallboxes. When used with the installation testing devices BENNING IT 200 or BENNING IT 130, it enables safety and functional testing of AC charging stations (wallboxes) for electric vehicles according to DIN VDE 0100-600 and DIN VDE 0105-100. It is compatible with 1- and 3-phase charging stations (EVSE) of charging mode 3 with Type 2 connectors.

The device facilitates simple functional testing of the wallbox and the connection of the installation device to the charging station. It simulates different current load capacities (codings) of 13 A, 20 A, 32 A, and 62 A for the charging cables. It also simulates various vehicle states: A (not connected), B (connected, not ready), C (charging without ventilation), D (charging with ventilation), and E (error, short circuit between CP-PE / PE disconnected).

Additionally, it analyzes the CP and PP signals (vehicle status, signal voltage, frequency, duty cycle). It measures voltage and phase rotation, with separate phase indicators (L1/L2/L3) indicated by three LEDs as soon as the charging station provides power. The device triggers the 30 mA AC and 6 mA DC residual current device with time measurement. It features a test socket and 4 mm sockets (L1/L2/L3/N/PE) for easy connection to the installation testing device. The EVSE locking system is checked from status B (release of the charging cable is blocked). It has a measurement category of CAT II 300 V and includes a protective case.
