A PDM (Power Distribution Module) is a device used to replace conventional relays and fuses in a vehicle electrical system. The Hardwire Electronics PDM takes inputs from physical switches, analogue voltages, or the CAN bus, and provides power to different electronic devices such as radiator fans, fuel pumps and head lights. The current being drawn from each connected device is continuously monitored. If the measured current is too high due to a fault, the PDM switches off the respective output to prevent further damage to the wiring loom or the connected device. The PDM can then retry the output to see if the fault has cleared.

A PDM (Power Distribution Module) is a device used to replace conventional relays and fuses in a vehicle electrical system. The Hardwire Electronics PDM takes inputs from physical switches, analogue voltages, or the CAN bus, and provides power as needed to different attached loads – such as radiator fans, lights or pumps. The current being drawn from each connected load is continuously monitored. If the measured current is too high due to a fault, the PDM switches off the respective output to prevent further damage to the wiring loom or the connected device. The PDM can then retry the output to see if the fault has cleared.
Solid State technology ensures maximum reliability, without the drawbacks of conventional mechanical relay and fuse systems. Vibration, water and dirt are no longer a problem.
Since its launch in 2019, the PDM25 has successfully been used in a range of applications – from drilling machines in ore mines, to top-spec drag race cars, to EV trucks, and even in industrial greenhouses to actuate ventilation windows. Allowing the user to configure the PDM to suit their own needs is one of its greatest strengths.
