Abstract: A circuit arrangement in an electrical device which contains a load which can be supplied with a direct-current voltage of lesser quality and electronic components which can be supplied with a direct-current voltage of greater quality, especially in a timing relay for supplying the device with energy from an alternating-current network by means of a transformer or voltage divider connectable with the alternating-current network and a subsequently connected rectifier arrangement. The rectifier arrangement connected after the transformer has an output at which there are connected a first supply branch and via a reverse current barrier a second supply branch containing smoothing means and a voltage stabilizer. The load which is to be supplied with the direct-current voltage of lesser quality is connected at the first supply branch and the electronic components to be supplied with the direct-current voltage of greater quality are connected at the second supply branch.
