PDM User Manual

Introduction

Link's Razor PDM is an advanced, fully programmable microprocessor-controlled Power Distribution Module.

It uses solid-state power devices, upgrading and replacing traditional relays and fuses to simplify wiring and better control power consumers.

Housed in a high-quality, sealed, CNC machined aluminium enclosure, with status LEDs for all 12 outputs, power, and temperature.

Configuration is carried out using the PDM Link PC software, where the user can combine any number of CAN and physical I/O to create a custom power control strategy.
