Ciocan20 Posted July 26, 2013 Share Posted July 26, 2013 As avea si eu nevoie de 3 alimentari pentru 3 circuite(un uC,un module de relee,un modul care comanda niste sensori).cine ma ajuta cu o schema pentru ca am nevoie de 3 tensiuni diferite.Alimentare uC=3,3v.Alimentare modul comanda relee=12v,Alimentare modul comanda senzori=10v sau 12v; Link to comment Share on other sites More sharing options...
Ticu Posted July 26, 2013 Share Posted July 26, 2013 Folosesti reteaua 230V sau acumulatori (pentru portabilitatea/independenta montajului) ?Ar fi util sa indici si consumurile maxime (mA) pentru cei trei consumatori. Link to comment Share on other sites More sharing options...
Ciocan20 Posted July 26, 2013 Author Share Posted July 26, 2013 ok folosesc reteaua dar trebuie sa folosesc o singura alimentare de la retea si restul,adica ce am zis mai sus,un circuit sa faca toata treaba,sa genereze toate tensiuniile alea dar si ele independente Link to comment Share on other sites More sharing options...

Marian Posted July 26, 2013 Share Posted July 26, 2013 @Ciocan20 n-ai inteles intrebarile colegului @Ticu, incerc sa reformulez eu:1-Ce sursa de alimentare a montajelor preferi, de la retea ( adica de la priza ) sau de la baterii?2-Ce consum in A sau mA are fiecare montaj in parte?

Ciocan20 Posted July 26, 2013 Author Share Posted July 26, 2013 de la retea normal.la uC nu stiu exact pentru ca nu m-am hotarat ce sa aleg si la celelalte doua aproximativ 200mA Link to comment Share on other sites More sharing options...
Ticu Posted July 26, 2013 Share Posted July 26, 2013 Pentru 12V te poti inspira de aici: http://www.electroschematics.com/6986/s ... -circuits/ iar pentru 3,3V de aici: http://www.eleccircuit.com/easy-power-s ... ransistor/ http://www.petervis.com/Raspberry_PI/Ra ... upply.html http://www.core.st/projects/AVR32_Start ... cheap.html sau un modul gata facut: http://www.miniinthebox.com/ams1117-3-3 ... 06982.html Link to comment Share on other sites More sharing options...
Ciocan20 Posted July 29, 2013 Author Share Posted July 29, 2013 Un convertor DC-DC buck nu se poate folosii?cum trebuie dimensionat pentru o intrare de 15v? Link to comment Share on other sites More sharing options...
leoncris Posted July 29, 2013 Share Posted July 29, 2013 Cate relee vrei sa comanzi cu ... 200mA ?Nu vrei sa explici exact ce vrei sa faci ? Link to comment Share on other sites More sharing options...
Ciocan20 Posted July 29, 2013 Author Share Posted July 29, 2013 10 relee trebuie alimentate.la 10v Link to comment Share on other sites More sharing options...
