Montaj Limitare Tensiune auto 12V>3V

Recommended Posts

Guest samedaniel

Cum se poate realiza un montaj care sa limiteze tensiunea de 12V de la instalatia electrica auto ,la 3V.

Poate aveti o schema ceva.

Ideea e sa se pastreze cat de cat intensitatea.

 

Va multumesc !

Se poate in comutatie,de ex LM2576,sau liniar,cu LM317.Acum depinde ce curent doresti la cei 3V.Sau daca nu cunosti curentul,macar spune ce vrei sa alimentezi cu 3V.

In cazul de fata as vrea sa alimentez o alarma care functioneaza alimentata cu 2 baterii 1,5v Ro3.Dar in general as vrea un montaj de limitare tensiune ,care sa pastreze pe cat se poate de mult intensitatea .Si as vrea ,daca sunteti amabil sa-mi spuneti ce presupune "comutatie" si "liniar".Multumesc !
