Product Datasheet


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. Each of the 4 outputs can supply up to 15A continuous load current. Higher loads can be driven by grouping outputs together. Each outputs can be triggered by CAN or a switch input and an optional master ignition switch input. 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.
