neagu Posted January 29, 2021 Share Posted January 29, 2021 Salutare tuturor, acesta dioda este de la un aparat de sudura, in catalog spune ca este de 60A. As vrea sa stiu daca este 60A pe brat sau nu, ma puteti ajuta cu această informație. Multumesc. Quote Link to comment Share on other sites More sharing options...
Marian Posted January 29, 2021 Share Posted January 29, 2021 30A per dioda. Quote Link to comment Share on other sites More sharing options...
neagu Posted January 29, 2021 Author Share Posted January 29, 2021 Uau, si astia spun ca aparatul de sudura are 200A, in el sunt montate trei diode cu seria mai sus menționate. Quote Link to comment Share on other sites More sharing options...
Marian Posted January 29, 2021 Share Posted January 29, 2021 Si trebui crezut tot ce pretind comerciantii? Quote Link to comment Share on other sites More sharing options...
neagu Posted January 29, 2021 Author Share Posted January 29, 2021 Parca arcul electric la un aparat de sudura incepe sa fie de calitate de pe la 80-90A, cu asta faceam treaba buna cu el cu electrod de 2,5, si o tensiune de 36v.

Florinel TV Posted January 29, 2021 Share Posted January 29, 2021 (edited) Si in secundar au diodele sa inteleg, am uitat de cand nu am mai reparat invertor de sudura Atunci ce IGBT are? Edited January 29, 2021 by validae litere Quote Link to comment Share on other sites More sharing options...
neagu Posted January 29, 2021 Author Share Posted January 29, 2021 Tranzistorii igbt au seria 60T65PES, sunt doua bucati. Quote Link to comment Share on other sites More sharing options...

Diodele sunt puse in paralel nu? 100A per tranzistor rezulta 200A limitat Dar maxim are 160A cred Quote Link to comment Share on other sites More sharing options...
