Power Distribution Unit

Power Distribution Units (PDUs) consolidate and protect electrical circuits within a vehicle, typically located in the engine compartment or passenger compartment. These units house high-current fuses and relays, distributing power from the battery and alternator to various vehicle systems. Modern PDUs often integrate circuit monitoring and diagnostic capabilities, utilizing sealed, corrosion-resistant housings and optimized wiring harness connections. Solid-state power fuses and built-in short-circuit protection are common features enhancing reliability and safety. Component designs prioritize thermal management to dissipate heat generated by high current loads.
