The ECUMaster PMU16 (AS) Autosport Version is designed for demanding customers and installations where reliability and robustness is priority. One of the main advantages of the PMU16 (AS) is continuous current sensing and self-resetting function if the current exceeds a defined level. All output state, voltage and current information can be logged and transmitted via a CAN bus to dash displays to inform drivers of potential problems.

Compared to the standard PMU16, 6 low side outputs have been added and are rated at 1 amp per channel. 14 of the main output channels are rated at 25 amps, with two output channels rated at 40 amps.

Autosport connectors represent the highest quality connector available and are the standard for professional motorsports and aerospace industries. The battery connection utilizes a RadlokTM connector rated to 200 amps that can be disconnected without the need for any tools. The output connector is a custom 18 pin, 12 gauge connector designed and manufactured specifically for Ecumaster. The unit features an IP65 environmental protection rating, permitting its use in the harshest of conditions, including dusty and wet environments.

An additional advantage of the ECUMaster PMU16 (AS) system is the ability to define logic for controlling outputs. This is done with data from analogue input channels or CAN bus data, and math operations can be defined for each channel. The PMU is also equipped with LED indicators to show the status of each output.
