Abstract
The invention relates to an apparatus ( ) for protection of electronic circuits with a decentralized power supply (PS , PS ). One object of the invention is to avoid damage to other loads (PN , PN ) which are still intact when a short circuit occurs in one load (PN , PN ) in the circuit. The apparatus ( ) comprises a number of loads (PN , PN ) which are supplied in a decentralized manner. One monitoring device (PSUP , PSUP ) in each case monitors a respective one of the load supply voltages (P , P ) and ensures primary-side fault disconnection of all the power supplies (PS , PS ) if a threshold value is undershot.
