Where it sits
The PBX 190 is the flagship of the PowerBox range, above the PowerBox PBX 90: 250 A continuous against the PBX 90's 120 A, 52 outputs against 36, plus four high-side channels rated to 48 V. If your car's electrical load fits within 120 A continuous and 36 outputs, the PBX 90 is the right choice. Mating connectors X1 to X5 are available from 909.
