Lazăr Bogdan Posted October 19, 2013 Share Posted October 19, 2013 Am o nelamurire. Daca am o pedalutza care cere 9V si 300mA , iar eu am un Adaptor de 9V si 500mA , ce se intampla? se arde? functioneaz?! Merci anticipat Link to comment Share on other sites More sharing options...
'mnezău Posted October 19, 2013 Share Posted October 19, 2013 Dacă tipul lui e care trebuie (AC, DC) şi polaritatea e aia bună, funcţionează. Amperajul trebuie să fie cel puţin egal cu cel cerut de pedală, valoarea lui putând fi mai mare. Link to comment Share on other sites More sharing options...
sam Posted October 19, 2013 Share Posted October 19, 2013 Va functiona fara probleme, la tensiune ai grija sa fie cea corecta si mai ales polarizata, curentul poate fi si mai mare. Link to comment Share on other sites More sharing options...
Popular Post ramurel Posted October 19, 2013 Popular Post Share Posted October 19, 2013 (edited) E ca și cum ai merge să-ți cumperi ceva de 300 de lei și ai 500 la tine... Edited October 19, 2013 by ramurel 10 Link to comment Share on other sites More sharing options...
Lazăr Bogdan Posted October 19, 2013 Author Share Posted October 19, 2013 Tensiunea este corecta , a fost masurata , polaritatea la fel. (miezul - , partea din afara + ). Amperajul ala de 500mA m-a speriat putin si nu vroiam sa imi ard pedalutza. Merci fain de aceste raspunsuri promte!!! Link to comment Share on other sites More sharing options...
sam Posted October 19, 2013 Share Posted October 19, 2013 (edited) Cum ti s-a spus deja, poti sa-i dai si 2 amperi, daca respecti tensiunea si polaritatea, esti 'safe'. Edit: For the record, vezi ca exista surse in comutatie si surse liniare. Nu e domeniul meu, iti pot explica alti colegi de forum mult mai bine diferentele daca te intereseaza.

Lazăr Bogdan Posted October 21, 2013 Author Share Posted October 21, 2013 DC si AC , presupun ca la asta te referi ? Link to comment Share on other sites More sharing options...
ady marius Posted November 11, 2013 Share Posted November 11, 2013 sursele in comutatie sunt alea usoare cu circuite integrate iar liniare sunt cele clasice prin inductie magnetica Link to comment Share on other sites More sharing options...
