Sziasztok
Segítségeteket kérném, hogy hol kapható nem csillagászati árin hagyományos EI vagy M vasas hálózati trafó. A geometriai méretei.
Vas pakett 78x65 és 27vastag A trafó teljes magassága csévével 53mm.
230V-24V kb 50w
Ez egy betegágy motorjait tápláló elektronika trafója. Linak CB10-03-OT-24 1996-os gyártású. Nem mai darab és örök életre tervezett csak egy villanyszerelési anomália kinyírta. Ami fontos, hogy ne zúgjon és kicsi legyen a vesztesége vagyis ne melegedjen üresjáratban.
Segítségeteket előre is köszönöm

Segítségeteket kérném a következőben: volt kollégám elhozta hozzám NAVON N260 navigácíóját javításra. Mivel kiszálló műszerész napi szinten használatban van. A probléma a következő: a gép bekapcsolás után lefagy. A Google segítségével kideritettem, hogy egy sd kártyára írható ROM file frissiteni képes a programot de sajnos csak N350 re találtam ami fel is telepűl de a kijelzőt nem vezérli. Ha valakinek esetleg megvan biztonsági mentésből akkor legyen szíves küldje el. Ha valakit érdekel akkor az N350 et felrakom a tanyára. Előre is köszönöm !
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?
