AiM EPM 8-Output Power Distribution Interface
The AiM EPM is a power distribution interface designed to work with current AiM dash and display systems. It replaces traditional fuse-and-relay arrangements by distributing protected power to multiple vehicle circuits through eight high-side outputs.
This is a power distribution module, not a standalone data logger, dash, ECU, sensor, or generic vehicle PDM. Confirm the AiM dash, vehicle wiring, current demands, protection requirements, and installation documentation before ordering or wiring.
Confirmed EPM features
- Outputs: Eight high-side outputs, rated up to 20 A each, with one output featuring a series diode.
- Total current: Maximum stated AiM EPM current of 120 A.
- Protection: Over-voltage, under-voltage, over-current, and over-temperature protection.
- Inputs: Pull-up +12 V, +5 V, analogue/digital, and pull-down input functions are listed.
- CAN: One AiM CAN Bus connection.
- Indicators: Eight configurable RGB LEDs, one PDM status indicator, and one PDM-on indicator.
- Connectors: One AMP connector and one Amphenol Surlok connector.
- Body: Anodised aluminium case.
- Protection rating: IP65.
- Dimensions: 122.0 × 94.6 × 46.1 mm.
- Weight: 400 g.
The product record does not specify the individual output pinout, fuse-equivalent setup, output derating, cable requirements, connector pin assignments, CAN configuration, or complete vehicle fitment list.
Installation and electrical checks
- Confirm the AiM dash or display system and the EPM connection requirements.
- Size each circuit, cable, connector, ground path, and protection arrangement for its real electrical load.
- Do not treat the 20 A output rating as permission to exceed vehicle, connector, wiring, or system limits.
- Confirm the total current requirement remains within the stated 120 A maximum and the relevant installation limits.
- Verify AMP and Amphenol Surlok connectors, power, ground, inputs, outputs, and AiM CAN wiring against the correct documentation.
- Keep high-current wiring away from heat, abrasion, water ingress, and moving components.
- Test each output, input, indicator, CAN connection, and protection response before competition use.

AiM EPM FAQ
What is the AiM EPM?
It is an AiM power distribution interface for distributing protected power to multiple vehicle circuits through eight high-side outputs.
How many outputs does the EPM have?
The product record lists eight high-side outputs, rated up to 20 A each, with a stated maximum total current of 120 A.
Does the EPM include a data logger or dash?
The current product positioning is a power distribution interface. Do not treat it as a standalone data logger or dash.
What communication connection does it use?
The product record lists one AiM CAN Bus connection.
What protection features are listed?
Over-voltage, under-voltage, over-current, and over-temperature protection are listed.
Is the EPM a universal vehicle PDM?
No. Confirm the AiM dash or display, vehicle wiring, output loads, connector pinout, CAN configuration, and installation limits before ordering or wiring.
