Globus 170 Helvi

Recommended Posts

Salut !

Pentru invertorul din topic, am cumpărat de la tme 6 buc. igbt-uri IKW50N60H3 și culmea este că sunt de proveniență China, ce sfat îmi dați să merg pe ăștia, sau să pun altceva.
Invertorul l-am cumpărat defect, iar igbt-urile se văd că au mai fost schimbate, știe cineva dacă modelul acesta de tranzistori sunt originali, ca de manual de service nici nu "îndrăznesc " să întreb.

Modelul acesta de IGBT-uri este mai nou decat aparatul, deci nu au cum sa fie cele originale. Se pare ca originalele au fost GP50b60pb1, vezi in linkul urmator:

Da optocuploarele sunt TLP250, am câteva bucăți sgw30n60 din kit-uri originale Telwin, dar parca nu ma îndur sa le utilizez.

Maine dacă am timp încerc sa-l alimentez, și sa vedem ce rezulta, asa la prima vedere e construit binișor.
