In professional motorsport, most teams use solid-state power distribution boxes to control high-current devices (fans, motors, pumps etc).
Making the loom for the FSAE car last year and using relays/fuses was a PITA after having used a proper PDU before.
Do any of you guys use a power box in your SAE cars? If you have, which did you go for? If you looked into it and chose not to, why?
