The Mectric Micro PDM4 is a smart 4 channel power distribution module designed to replace mechanical relays and fuses in aftermarket automotive electrical circuits. The device is fully CAN supported allowing for seamless integration with other devices. CAN transmit and receive protocols are fully user definable. Each of the 4 outputs can supply up to 15A continuous load current. Higher loads can be driven by grouping outputs together. Input & output logic is fully programmable. The µPDM4 is constructed from AEC-Q100 Automotive Grade components, ensuring it's reliability in harsh environments.

In applications where installers may need to add a small number of power circuits but don't require the size, cost or complexity of a full scale PDM. The Micro PDM4 is perfect for coupling with new engine harness builds or when adding a new set of fans or pumps to a vehicle.

Fully designed, manufactured and assembled in Australia.

Programming

CAN Based Programming

The µPDM4 is fully capable of real time configuration and firmware updates over CAN Bus. This is done using a range of supported USB to CAN adapters and our MectiCal calibration software


Direct CAN Control

The  μPDM4 includes a range of predefined CAN control frames that allow devices such as ECU's or Display Dash's to directly control the outputs without the need for any physical switch inputs.

Direct control frames allow direct override of:

  • Output enable
  • Output duty & frequency
  • Output current limits & retries
  • Output enable in 16 bit LSB format compatible with Emtron Tx Datasets

See the product datasheet for detailed information.
