SURGE PROTECTION AND DISCONNECTION DEVICE FOR AUDIO-VIDEO DEVICES

Typical of the surge protection and disconnection device for audio-video devices is that it performs two functions, the protection of users against overvoltages within the 230 V mains network and overvoltages on the video antenna cable, which is connected to the antenna input of the TV set (e.g. upon atmospheric discharge) as well as reducing the power consumption so that it completely disconnects the user from the mains network, which would otherwise operate in the stand-by mode. It also includes an IR receiver, by which it receives signals from the remote control, controlling the switching of the relay for disconnecting from the mains network. Naprava za prenapetostno zascito in izklop avdio-video naprav je znacilna po tem, da opravlja dve funkciji, zascito porabnikov pred prenapetostjo na omrezju 230V in prenapetostjo na video antenskem kablu, ki se priklopi na antenski vhod TV aparata (npr. ob udaru strele) in zmanjsanje porabe elektricne energije tako, da porabnike, ki bi sicer delovali v rezimu pripravljenosti (stand-by), popolnomaizklopi iz elektricnega omrezja, da vsebuje tudi IR sprejemnik, s katerim sprejema signale iz daljinskega upravljalnika, ki krmili vklop releja za izklop iz elektricnega omrezja.
