Stationary Equipment

Replace the fuses, relays and relay outputs in 12/24 V DC control cabinets with one solid state PDM, for battery storage, industrial machinery and equipment in harsh environments.

Not every PDM goes in a vehicle. Battery storage units, industrial machinery and equipment in harsh environments often run their control circuits on 12 V or 24 V DC, through cabinets full of fuses, relays and PLC outputs. A Hardwire PDM replaces them with one sealed solid state unit, with its own logic and a CAN connection to the rest of the system.

Battery energy storage

Switching and protecting the circuits inside each battery unit.

Industrial machinery

Retrofitting recycling and processing machines with simpler, more reliable electrics.

Equipment in harsh environments

A 12/24 V alternative to a PLC and relay outputs where water, dust and vibration are a problem.

What it replaces

  • Fuses and relays in the control cabinet, with one protected output for each circuit.
  • Simple PLC logic, using the PDM's own logic functions, timers, tables and scripts.
  • Wiring to individual switches, which becomes a two-wire CAN bus when paired with CAN keypads.

How it helps

  • Every circuit is switched and protected electronically, with no fuses to replace.
  • Current monitoring on every output, with low current detection to find failed loads.
  • CAN connects the PDM to the system's controller or battery management system, for monitoring and diagnostics.
  • A global cut-off turns every output off at once, for example on an emergency stop or low voltage.
  • IP67 sealed, solid state, and works from -55 °C to 90 °C.
  • Outputs, logic and fuse ratings are changed in software, not by rewiring the cabinet.

Hardwire PDMs switch DC circuits from 4 to 32 V. To switch mains AC loads, a PDM output can drive an external relay or contactor.

Building more than one

The same configuration can be loaded onto every unit and password protected, and the PDM stores lifetime statistics and trip counts to help with servicing. See power distribution for vehicle and equipment builders for more.
