Recommended Posts

Buna ziua !

Am la reparat un invertor rusesc cu igbt-urile defecte . Poate cineva sa imi zica cu ce sa la inlocuiesc  , pentruca nu gasesc nici o referinta la ele ,

Atasez si 2 poze :

Multumesc !

Dupa solicitarea unui coleg pun cateva poze cu interiorul acestui invertor rusesc , Cobalt MMA-320DC .

Totodata intreb care ar fi puterea reala daca are doar 2 igbt-uri de 60A ? 320A dupa cum arata pe eticheta  in nici un caz cred !

Cred ca se regaseste si sub alta denumire si culoare.....cu mici modificari la placa si la unele piese adica un condensator in plus sau minus..:rade: !!

Model apropiat Stromo SW250 ...una din  probleme a fost cu placuta verticala cu driverele de la igbt....Alte probleme si aici pe forum :
