The EV charger equipped with PEN protection actively monitors the electrical system. In the event of a fault, it automatically disconnects all poles, including the earth conductor.
Internally, the charger’s design incorporates a contactor that isolates the ground. When the PEN line is disconnected, the contactors KM1 and KM2 are immediately and automatically disengaged. Only a minimal leakage current, less than 1mA, flows between CP and PE to the L line. This leakage current is below the threshold of human perception, ensuring there are no safety risks for individuals using the charger.
When the EV charger operates simultaneously with other household appliances, the DLB box ensures the dynamic balance of the total household current. This feature guarantees the safety of electricity and prevents home overload, allowing for efficient and secure charging of your electric vehicle.​
