DC Earth-Fault Detector for EV Quick Charger

DC Earth-Fault Detector is an effective protective measure during the quick charging process to prevent accidents associated with electrical malfunction, like electric shock to living organisms, damage to devices and risk of fire.

Redesign of the detector part is not needed. The DC Earth-Fault Detector suits for quick charging devices in Europe and USA. It is easy to handle, compact in size and indicates a leakage via LED signal. Moreover, a high quality noise filter is mounted on the device that makes it resistant to inverter noise.
