What Do Power Distribution Modules Do?

Power Distribution Modules (PDMs) are essential devices used to manage and distribute electrical power efficiently across systems and applications. They not only allocate power to multiple components but also offer integrated protection, monitoring, and control functionality.

The key functions of power distribution modules include:

  1. Power Distribution: PDMs draw electrical power from a main source—such as a battery or generator—and distribute it to various loads or subsystems. These might include lighting, sensors, motors, communications equipment, and more.
  2. Circuit Protection: PDMs are designed with built-in safety mechanisms such as fuses, circuit breakers, and overcurrent protection to safeguard against electrical faults, short circuits, and overloads. These features are critical to ensuring long-term system safety and reliability.
  3. Diagnostic Information: When fitted with CAN-enabled plug-in components, PDMs become “smart” systems capable of delivering live diagnostics. They can report:
    • Voltage levels
    • Temperature data
    • Fault Codes

This functionality simplies troubleshooting and aids preventative maintenance. 

Why Should You Consider Designing in a Power Distribution Module?

The advantages of incorporating a PDM into your electrical system include, but are not limited to:

  • Seamless integration with existing vehicle platforms
  • Simplification of wire harnesses, reducing both complexity and system weight
  • Ability to expand or scale system functionality without escalting costs
  • Improved reliability and a reduction in ongoing maintenance needs

Applications of PDMs

The versatility and robustness of hardwired power distribution modules make them ideal for a wide range of use cases, such as:

  • Medium & Heavy-Duty Lorries
  • Agricultural & Construction Machinery
  • Buses & Recreational Vehicles (RVs)
  • Powersports Vehicles
  • Marine Electrical Systems
  • Electric Vehicles (EVs)
  • Lawn & Garden Equipment
  • Standby Power Generators
