6.6 kW OBC and 1.5 kW DC/DC in one IP67 enclosure






The GC-INT-6.6KW-1.5KW integrates a 6.6 kW AC on-board charger and a 1.5 kW DC/DC converter (14 V, 107 A) in one IP67 enclosure. It charges 72 V to 540 V traction batteries and supplies the vehicle 12 V system from the same unit, saving space, wiring and installation time. It communicates over CAN 2.0B.
