sursa cu BU508

Recommended Posts

am niste surse de 125w cu BU508, dar imi trebuie de 200-300w si cam 120v pentru telealimentare switchuri. Solutia functioneaza dar un alimentator nu tine mai mult de 20-30 switchuri. Daca montez inca un tranzistor in paralel cu celalat mai rezolv ceva? Sau stie cineva de unde pot cumpara o sursa de minim 200w?Multumesc.

o alta solutie este sa fac sursa liniara cu traf...dar nu gasesc o schema care sa stabilizeze 120v si sa aibe si protectie la scurt...sau macar un fel de protectie la scurt fara stabilizare.
