- La acesta sursa se regleaza atat tensiunea cat si curentul

Pe scurt:
1. In: DC 7-32V
2. Out:DC 0.8-28V continuously adjustable
3. Curent constant: 0.2-8A (max 10A - ajustabil)
4. Current iesire: 8A (max 10A - testat)
5. Power Max 300W
6. Am pus in ultima poza un test cu sursa la un curent MAXIM de 10A (sarcina artificiala de 10A la 5V)

= Atentie! =

Aceasta sursa nu suporta varfuri de curent mai mari decat cele specificati aici in detalii tehnice

Aceasta sursa nu suporta regim tranzitoriu (pornire/oprire) ale sarcinilor inductive al caror curenti (varfuri) depasesc specificatiile sursei => se va distruge!

Prin diferite metode, se poate reduce efectele regimului tranzitoriu al sarcinilor inductive. De ex: O dioda rapida de putere polarizata invers, filtre RLC sau LC . . . (calculate la acel regim tranzitoriu) . . . .

Nota: Peste 80W sau peste 75-80C (temperatura radiatorului), necesita racire suplimentara cu un ventilator.
