In the case of a device for controlling the power of an electrical load, especially in motor vehicles having an electrical power source, having a clock generator, having an output stage which receives the clock pulses from the clock generator and has a switch in series with the electrical load, and having a short-circuit monitor which measures the voltage at the junction point of the electrical load and opens the switch if the voltage exceeds a predetermined threshold value, the short-circuit monitor can be controlled by the clock generator and becomes effective during the clock-pulse generation in order to identify reliably a short circuit on the electrical load.
