Metrel A 1732 Mode 3 Mode 4 EVSE Charging Station Adaptor

The Metrel A 1732 DC EVSE Adapter is a specialised test adapter designed for comprehensive electrical safety, functional testing, commissioning, and diagnostic evaluation of both DC EVSE (Mode 4) and AC EVSE (Mode 3) charging systems. Supporting CCS2, CHAdeMO, and Type 2 AC interfaces, it enables technicians to initiate and monitor communication protocols, measure voltages and currents, simulate EV-side behaviour, and trigger fault conditions to verify EVSE response. When paired with the MI 3155 EurotestXD, it provides full protocol logging, advanced measurement features, and automated testing workflows.

In conjunction with Instaltest XD MI 3155 (not included)

Mode 4 – DC EVSE (CCS2 & CHAdeMO)
