releu 24v

Recommended Posts

Sper sa fie identice, adica rezistenta bobinelor sa fie egala, ca sa se repartizeze egal pe ele tensiunea de 24V.

Ai mai putea pune in serie cu releul de 12V o rezistenta de valoare egala cu rezistenta bobinei.

Se alimenteaza bobina releului de 12V,in serie cu o dioda zenner PL12Z(sa fie de 1W).Pe bobina releului,conectat neaparat o dioda 1N4007,in polarizare inversa(sa taie virfurile de tensiune la deconectare,ce se autoinduc in bobina releului),iar pe dioda zenner un condensator,intre 100-500nF,sa taie zgomotul produs de aceasta.

Poate n-ar strica chiar un electrolitic de cateva zeci-sute micro, in paralel cu zenerul, ar ajuta la cuplarea mai rapida a releului. Condul, fiind descarcat, ar sunta zenerul, bobina ar fi  alimentata cu 24V, foarte scurt timp, pana cand condul se incarca prin infasurarea releului.
