Sziasztok
Egyenlőre tanácstalan vagyok hogy mit tegyek.
Azért írok hátha találkozott valaki már hasonló
dilemmával.
Találtam jó pár darab kondit újjak de kinézetre
úgy néznek ki mintha a végét járnák fólia
fel van húzódva rajtuk és méréssel 220 helyett
190u-t mérek ESR méréssel nem vagyok teljesenn képben
de egy profi műszerrel 1Khz alatti mérőfrekin
0.3-0.4ohm 220u/35v 105fok cel.-os szerintetek
kuka vagy nyogodtann használható.
Üdv Kiss
Hi,
Could anyone explain me or send a diagram explaining how this kind of supply works :
A LOK4801-2R can convert either 100-240V AC or 90-250V DC into 48VDC
After tearing down, i can see a bridge rectifier , a smps MOSFET, a plulse transformer
Any diagram to refer to ?

Tisztelt kollégák!
Ma vettem a piacon egy címben szereplő távirányítót a lomostól. Valaki tudna e kódokat hozzá valahol, vagy gyors keresési módszert véle?
Sajnos a google nem vezetett nálam eredményre. Köszönöm!
Üdv!

Üdv! Sziasztok!
Kapatam játszani egy projektort. Az izzó hibás, 30-40 ezer Ft-ot nem ér. El lehet indítani a gépet izzó nélkül? Gondolom figyeli az izzót. Ha igen, megnézném, mit tud LED-del, van pontszerű, de nagy teljesítményű LED-em.
Üdv: Jácint
