Abstract
The invention relates to an apparatus (1) for protection of electronic circuits with a decentralized power supply (PS1, PS2). One object of the invention is to avoid damage to other loads (PN1, PN2) which are still intact when a short circuit occurs in one load (PN1, PN2) in the circuit. The apparatus (1) comprises a number of loads (PN1, PN2) which are supplied in a decentralized manner. One monitoring device (PSUP1, PSUP2) in each case monitors a respective one of the load supply voltages (P1, P2) and ensures primary-side fault disconnection of all the power supplies (PS1, PS2) if a threshold value is undershot.
Claims20
An apparatus for protection of electronic circuits comprising:
- a first and a second power supply;
- a first and a second load associated with the first and the second power supply;
- and
- a monitoring circuit for monitoring the first and/or the second load and/or the first and/or the second power supply, wherein the monitoring circuit controls and/or switches the first and/or the second power supply.
