AEM PDU-8 Eight-Channel Power Distribution Unit

The AEM PDU-8 Power Distribution Unit is a CAN-based solid-state module that provides eight high-side outputs for switching control of various vehicle systems. Originally designed for EV applications and now available for internal combustion engines, the PDU-8 eliminates traditional fuses and relays while simplifying wiring, reducing weight, and increasing system reliability. It's the ideal solution for controlling fans, fuel pumps, lights, and other electronically switched devices.
