ECUMaster newly developed PMU unit provides 16 high current outputs (and use of multiple units if more outputs are required).  
 
One of the main advantages of the PMU is continuous current sensing and self-resetting functionality if current exceeds the defined level. All output state, voltage and current information can be logged and transmitted via CAN bus to dash displays to inform drivers of potential problems. An additional advantage of the PMU 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. With use of CAN bus keypads or steering wheel switches, all wiring is vastly simplified and lightened. Two unique features are the inbuilt accelerometer and gyro for logging and “inertia switch” in case of accident.
