Configurable
Configurable dc power distribution modules (PDMs) from Littelfuse are dust-tight, waterproof, and proven to perform in the harshest environments where commercial vehicles operate. Our full-sized Flexible Electrical Center (FLEC) accommodates more than 25 automotive fuses, diodes, and relays, and our compact MiniFLEC bolsters the performance of the main PDM module. Each configurable PDMs is internally bussed, connectorized, and comes with a printed circuit board (PCB) to coordinate circuit protection and current flow. For EVs, we also offer a High Voltage Power Distribution Unit that accommodates bus bars and sensors.

Configurable PDMS work well in these types of vehicles

  • Trucks
  • Street Trucks (e.g., Snowplow, Bucket, Garbage, Sweepers)
  • Buses and RVs (e.g., School, Commercial, Transit, Motor Homes)
  • Construction (e.g., Backhoes, Pavers, Bulldozers, Compactors)
  • Agriculture (e.g., Harvesters, Combines, Tractors)
  • Emergency (e.g., Ambulance, Fire, Police)

Features and Benefits of Our Hard Wired PDMS

  • Sealed power distribution modules, hardwired to accept 280-style components (MINI fuses, relays, circuit breakers, diodes, shunts, etc.) PDMs accept Delphi Metri-Pack 280 terminals, cable seals and cavity plugs. Available as HWB18 (accepts 9 two-bladed components) and HWB60 (accepts 30 two-bladed components).
  • The elimination of internal bussing allows user to customize their own circuitry, with direct wire-to component connections. User can install any mini (280 style) circuit protection component.
  • Compact size. PDMs are a perfect fit for accessory circuits, overflow circuits from main PDM, or a main module on smaller vehicles.
  • IP67 sealed units can be installed virtually anywhere on the vehicle. Stands up to roadsplash and salt spray, and gives robust protection to devices.
  • Terminal position assurance (TPA) locks give secondary locking protection of the wire leads, which aid in prevention of leads from being pulled out. TPAs snap onto the back of the PDM after wires are installed, and do not interfere with the cable seals needed to ensure IP protection. Easy to connect. Wires plug into the back of the unit using industry-standard Delphi Metri-Pack Series 280 tanged terminals.
