Product Description

PDM25

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.

  • Peak fuse and High fuse thresholds can be set to allow

  • for inrush current. 

  • Trip Mode can be set to Instant (output trips immediately

  • if the current exceeds the threshold) or Normal (acts like a normal physical fuse and allows short current spikes). 

  • Outputs can be configured to stay on for a specified time after the input is removed, useful for radiator fans or water pumps. 

  • Outputs can be retried multiple times after an over-current event is detected.

  • 200Hz PWM on each output, with variable duty cycle mapping. 

  • Soft start on each output for smoother turn on of devices. 

  • Advanced logic functions can be made to control the output as desired.
