Traditionally, fuses and relays served all of those purposes, but they have many disadvantages like complicated wiring looms, sensitivity to vibration/temperature, and difficult diagnostics. All of these problems can be solved by using intelligent power management units (PMUs). Our newly developed PMU unit is at the forefront of technology. It 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. There must be a CAN connection to programme outputs.
