UPS GUARD 600A

Recommended Posts

Schemele astea se gasesc mai greu, ce probleme ai cu UPS-ul ? In primul rand sa verifici starea acumulatorului daca are mai mult de 2-3 ani.Asta e primul care cade. Pentru restul de defecte nici nu trebuie musai schema, tranzistorii se gasesc si pot fi testati usor, cel mai frecvent se scurtcircuiteaza omorand si acumulatorul, fiindca sigurantele fuzibile sunt supradimensionate badaran :nebunrau:

Ma interesa transformatorul din el. Are vreo 6 fire in primar. Vreau sa -l folosesc la un incaractor auto pentru baterie.

Acele fire sunt pentru stabilizarea de tensiune in trepte.Daca vrei sa-l folosesti ca redresor (foarte bun ca atare, si eu am unul chiar acum in functiune) poti folosi acele prize pentru a regla tensiunea in secundar la aproximativ 12V.Sa folosesti doar doua diode la redresare, e mai eficient si ieftin.Folosesti astfel priza mediana a transformatorului.
