Benning EV 3-1. The Wallbox tester and measurement adapter Benning EV 3-1 enables easy and quick functional testing as well as troubleshooting of wallboxes. In conjunction with a suitable installation testing device, the safety and functional testing of AC charging stations (wallboxes) for electric vehicles can be demonstrated in accordance with DIN VDE 0100-600 and DIN VDE 0105-100 standards. Compatible with 1- and 3-phase charging stations (EVSE) of charging mode 3 with Type 2 connectors. Allows for simple functional testing of the wallbox and the connection of the installation device to the charging station. Simulates different vehicle states: A (not connected), B (connected, not ready), C (charging without ventilation), E (error, short circuit between CP-PE). Displays output voltage (L1/L2/L3) and vehicle states (B/C) via colored LEDs. Checks the EVSE locking system from status B (release of the charging cable is blocked). 4 mm sockets (L1/L2/L3/N/PE) for easy connection with installation testing devices. 4 mm socket (CP signal) for analyzing the CP signal via an oscilloscope/multimeter. Usable with all common charging stations (wallboxes) with charging sockets and permanently connected Type 2 charging cables. Due to its ease of use, it can also be operated by electrically instructed persons (EuPs). Measurement category CAT II 300 V.
