3 GX400 rev.1 – 400W Hi-Fi Audio Amplifier | www.forum.tehnium-azi.ro

Caracteristici tehnice

(ATENTIE!!! curentul de mers in gol pentru tot amplificatorul se va ajusta NUMAI dupa anclasarea releului de pe iesire in domeniul 100...150mA)

Sursa de alimentare:

Obs!

1. Valorile componentelor din schema sunt recomandate pentru alimentarea a doua montaje GX400.

2. Condensatoarele de filtraj vor avea tensiunea nominala de 80V sau 100V.

3. Optional se poate utiliza un circuit de softstart pe alimentarea transformatorului T1.
