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. Link to comment
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. Link to comment
Marian Posted January 29, 2021 Share Posted January 29, 2021 Si trebui crezut tot ce pretind comerciantii? Link to comment
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 Acum 57 minute, neagu a spus: Uau, si astia spun ca aparatul de sudura are 200A, in el sunt montate trei diode cu seria mai sus menționate. Ce finali are? Link to comment
mac01 Posted January 29, 2021 Share Posted January 29, 2021 N-are finali...ca nu-i amplificator audio. Link to comment
Florinel TV Posted January 29, 2021 Share Posted January 29, 2021 Acum 2 minute, mac01 a spus: N-are finali...ca nu-i amplificator audio. Si atunci cum se numesc IGBT-urile nu cred ca se spun sursa Link to comment
Marian Posted January 29, 2021 Share Posted January 29, 2021 IGBT-uri... Sau tranzistori din primar. Link to comment
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 Link to comment
neagu Posted January 29, 2021 Author Share Posted January 29, 2021 Tranzistorii igbt au seria 60T65PES, sunt doua bucati. Link to comment
Florinel TV Posted January 29, 2021 Share Posted January 29, 2021 1 oră în urmă, neagu a spus: Uau, si astia spun ca aparatul de sudura are 200A, in el sunt montate trei diode cu seria mai sus menționate. Diodele sunt puse in paralel nu? 100A per tranzistor rezulta 200A limitat Dar maxim are 160A cred Link to comment

Florinel TV Posted January 29, 2021 Share Posted January 29, 2021 3 X 60 = 180A deci cum am spus maxim 160A Link to comment
Marian Posted January 29, 2021 Share Posted January 29, 2021 Si de unde ma rog scosasi cifra aia? Link to comment
