Stabilizing unit for load current in electrical consumer, such as light emitting diodes in vehicle power supply system of passenger vehicle, comprises controllable current regulator, which is aligned to set in current circuit

摘要

The stabilizing unit comprises a controllable current regulator, which is aligned to set in a current circuit and to regulate the load current to a desired value corresponding to an input signal (V-reg). An electrical surge detection unit is provided, which is aligned to compare the terminal voltage applied through the consumer and the current regulator with a predetermined electrical surge threshold value. An independent claim is also included for a vehicle power supply system with supply devices.
