MoTeC offers cost-effective PDM15 and PDM30 power distribution modules (PDMs) suitable for power management. Housed in robust magnesium casings with standard waterproof connectors, these entry-level units enable a broader range of racers to benefit from this intelligent technology. The units provide electronically switched power to various systems in a vehicle, such as motors, lights, solenoids, even electronic control units (ECUs) and data-acquisition systems. The PDM15 and PDM30 provide user-defined, software-driven control over the entire vehicle’s power needs and can be programmed to make smart decisions on the fly. For example, they can restart devices automatically after a short circuit, switch to a reserve pump if a main pump fails, and systematically shut down devices if battery voltage drops. PDMs communicate with other devices in the car via CAN and provide extensive diagnostics, including over-current errors. The monitoring of these values, especially via telemetry during a race, is helpful in the early detection of faults.
