Features and Benefits

EV wallbox chargers up to 35kW

On the grid side, the 4-line choke can be installed as 3 phases and neutral
On the vehicle side of the charger (DC charging), 2 windings of the choke are connected in series or parallel
Complies with choke-related requirements in IEC/EN 61851-1: Electric vehicle conductive charging system, IEC/EN 61851-21-2 (AC charging) & IEC/EN 61851-23: (DC charging)
Complies with choke-related requirements in UL 2202 Electric Vehicle (EV) Charging System Equipment
