The Ecumaster PMU-16 AS is the Autosport-connector variant of the PMU-16, engineered for FIA-level motorsport where sealed MIL-grade connectors, IP65 environmental protection, and documented power distribution are required by technical regulations or team standards.
It carries the same 100-function CAN logic engine, open CAN2.0B architecture, and per-output current monitoring as the standard PMU-16, but delivers higher peak output ratings (2×40A for electric power steering or large radiator fans), adds 6 low-side 1A outputs for ECU digital inputs and relay coil switching, and includes 256MB internal data logging as standard — no DL suffix needed. The Radlok 200A tool-free battery connector allows isolation of the full power supply without tools, satisfying FIA electrical shut-off requirements.

What You Can Do With It
- Meet FIA electrical connector requirements — Deutsch Autosport connectors (MIL-DTL-38999 class) satisfy FIA technical regulations and team standards for sealed, vibration-resistant power distribution connections
- Tool-free electrical isolation — Radlok battery disconnect allows the main power supply to be broken without tools in seconds, satisfying FIA Article 253 requirements for accessible electrical shut-off
- Drive electric power steering directly — 2×40A outputs handle EPS pumps that would require paralleled outputs on the standard PMU-16
- Switch ECU inputs from the PMU — 6×1A low-side outputs drive ECU digital inputs, relay coils, and active-low sensors — not available on the standard PMU-16 or PMU-16DL
- Log PMU data without an external logger — 256MB internal logging captures all output states, currents, and voltages at up to 500Hz internally, without requiring an AiM or Bosch Motorsport datalogger
Product Family
| Model | Outputs | Total current | Internal logging | IP | Connectors |
|---|---|---|---|---|---|
| PMU-16 | 10×25A + 6×15A | 150A | No | IP60 | 39-pin auto + M6 stud |
| PMU-16DL | 10×25A + 6×15A | 150A | 256MB | IP60 | 39-pin auto + M6 stud |
| PMU-16 AS | 14×25A + 2×40A + 6×1A LS | 150A | 256MB | IP65 | Autosport + Radlok |
| PMU-24DL | 10×25A + 6×15A + 8×7A | 170A | 256MB | IP60 | 39-pin auto + M6 stud |
The PMU-16 AS is a completely different physical form factor from the rest of the family: 177×84×46mm versus 131×112×32mm. Plan mounting accordingly.

FAQ
What does the AS in PMU-16 AS stand for?
AS stands for Autosport — the Deutsch Autosport connector standard used throughout the unit’s signal connectors. This is the same sealed, MIL-grade connector used in FIA GT3, LMP, and WRC cars, and in aerospace applications. The Autosport connectors provide superior vibration resistance and IP65 sealing compared to the standard 39-pin automotive connector on the PMU-16.
What is the Radlok connector and why does it matter?
The Radlok is a Stäubli power connector rated to 200A, designed to be disconnected and reconnected without tools. On the PMU-16 AS, it serves as the main battery isolation point. FIA Article 253 requires an accessible electrical shut-off that can be operated quickly — the Radlok satisfies this without the need for a separate battery isolator switch.
Does the PMU-16 AS include data logging?
Yes. Unlike the standard PMU-16, the AS version includes 256MB of internal data logging as standard — the same DL hardware that appears as a separate model in the standard family. All output states, currents, and voltages can be logged at up to 500Hz internally, without an external logger.
How is the PMU-16 AS physically different from the PMU-16?
It is a completely different form factor: 177mm long, 84mm wide, 46mm deep, and 527g — versus the standard PMU-16 at 131×112×32mm and 345g. The Autosport connector housings and Radlok battery interface account for the additional size. Mount it with this in mind when designing the power distribution bay.
