Sziasztok!
A címbeli szerkezetet készülök venni. Van valakinek ilyen gépe? Milyen tipusút érdemes venni? Mennyire üzembiztosak ezek(gondolom mind kínai)? Ha valakinek van tapasztalata vele, légyszi írja meg! Köszi.
Üdvözlök mindenkit!
Nemrégiben arra adtam a fejem, hogy biztonságtechnikai munkákat is vállalok.
Összeakadtam egy FAZ 3000 típunévre hallgató rádiós riasztóközpontal és a hozzá tartózó kiegészítőkkel. Rettentő egyszerű konfigurálni szinte 0 hibalehetőség, DE a rádiós mozgásérzékelők mégsem riasztanak. Van lehetőség tesztre: lefut és jó: Van lehetőség zavarkeresésre: lefut és jó. Tudna valaki segíteni?
Working on a speed charge battery maintainer for small engines battery. Heat sink had (2) S2025R T0-220 type components on it. Seems they are an SCR and I have 57 ohms on 1 and 3 pin, so seem they are short. Cant get these anymore but installed S4025R which seems to be better replacement. Before replacing, heat sink seemed to be really hot after replacng on on
board 10 amp automotive slot type fuse, so seemed these SCR were bad, getting hot woth no load.
Standby LED not lighting with new SCR's installed. Old ones did not have heat sink compound on them, so I used some to better transfer heat. I saw the input of the 7805 1 amp
regulator IC has short, so removed it, and its not shorted, but the feed to it comes from the IC chip on board, a EM78P41 BWD20J. Data sheet for EM78P41 is online. They have pin 16 going to pin 1 of the 7805 regulator. Actual reading on pin 16 to ground is 2.5 ohms. I suspect this IC is shorted output. Is there chance to replace IC or is this repair finished?

üdv: ez a páka csak 300W-os, elég kis teljesítményű
Vennék hozzá nagyobb fejet, de gondolom, ehhez a táp részét is át kellene alakítani
Csinált ilyet valaki?
Rajzom nincs hozzá (a Wantedbe feltettem)
