After successfully bringing the first series-produced 22 kW On-Board Charger into the market, BRUSA continues to address the needs from its customers in the best possible way by offering OBC7, the next generation of all-in-one charging solution.
The galvanically isolated device focuses on increased environmental capabilities and operation lifetime to address a wide spectrum of applications: cars, light-, medium- or heavy-duty trucks, the OBC7 reaches a unique versatility. Also, the device scope isn’t restricted to AC charging: in fact, the integrated PLC controller enables support of DC charging control using CCS1 or CCS2 inlets. The vehicle DC contactors can also be driven directly by the device, providing in addition to vehicle inlet management features the best all-rounder solution available on the market.
