REDUKTOR PREDKOSCI OBROTOWEJ WENTYLATORA 12V

Reduktor zmniejsza obroty wentylatora co obniża hałas generowany przez wentylator.

Podłączenie jest banalnie proste, z jednej strony reduktor wpinamy pod zasilanie 12V a z drugiej do wentylatora.

Pasuje do wentylatorów 12V DC o maksymalnym poborze 0,30 A (zalecane max 0,25A) znamionowo.

Posiada typowe wtyczki 3 pin.

Reduktor jest typu rezystancyjnego - oporność około 40-44 omy. Długość przewodu około 10-11cm.

Zmniejszenie obrotów (napięcia które dostaje wentylator) zależy od poboru prądu znamionowego przez wentylator i orientacyjnie dla przykładu (nasze testy) wynosi:

z wentylatorem o małym poborze prądu (0,11 A znamionowo przy 12V na wejściu) napięcie wyjściowe za reduktorem wynosi około 9V czyli wentylator ma wyraźnie mniejsze obroty, jest cichszy
z wentylatorem o większym poborze prądu (0,30 A znamionowo przy 12V na wejściu) napięcie wyjściowe za reduktorem wynosi około 6V czyli mniej więcej połowa mocy wentylatora

W przypadku słabszych wentylatorów, w razie potrzeby dalszego zmniejszenia obrotów można zastosować 2 reduktory szeregowo.

W przypadku gdy stosujemy rozdzielacz (z jednego zasilania na 2 lub więcej wentylatorów) reduktor należy wpiąć przed samym wentylatorem - poprzez jeden reduktor zasilamy jeden wentylator. W galerii pokazano przykład podłączenia 2 wentylatorów (zastosowano 2 reduktory) przez rozdzielacz z jednego zasilacza 12V.

W razie potrzeby można zakupić większą ilość reduktorów (1 szt kupiona = jeden reduktor)

W magazynie 9 szt.
