Stefan Andrei Lupu Posted October 23, 2016 Author Share Posted October 23, 2016 contactul mobil ar trebui sa comute la actionarea reglajului pentru voltaj ? sau cum ar trebui sa functioneze ? Quote Link to comment Share on other sites More sharing options...
Stefan Andrei Lupu Posted October 23, 2016 Author Share Posted October 23, 2016 Din ce vad aveti dreptate, din masuratori imi da ca tranzistorul TIP42C este strapuns intre B-C ... am sa il inlocuiesc sa vad rezultatul Quote Link to comment Share on other sites More sharing options...
validae Posted October 23, 2016 Share Posted October 23, 2016 Categoric acolo apar problemele, autoinduc?ia motora?ului str?punge acele tranzistoare uneori, chinezul nu s-a obosit s? le protejeze prea mult... Quote Link to comment Share on other sites More sharing options...
