ABSTRACT:
In a circuit arrangement for feeding electrical users with a DC voltage, a constant-current fed switch controller is followed by a voltage converter. Given such a circuit arrangement, difficulties can arise when users are fed which, given a change of the input voltage, take a constant power, as is the case given voltage converters having a regulated output voltage. In order to make the circuit arrangement as insensitive as possible to overload conditions, the circuit arrangement is provided with a device for limiting the input power of the voltage converter. The circuit arrangement can be employed with particular advantage for feeding intermediate locations in communications transmission devices.
