Recommended Posts

Am bagat "lunetele in priza" si am aflat precis (scrie mic, mic pe el):

Am vazut ca ati folosit tot diodele BYX10, desi frecventa este mult mai mare. Nu sunt probleme datorate Trr (reverse recovery time) mare?

Asa am pus, deoarece erau in aparat. Am verificat temperatura diodelor si a rezistentei R1, careia i-am crescut puterea

 de la 0,33W la 0,5W. De fapt am lucrat la "impuse" pentru ca in locatia unde am facut modificarea, atelierul este cam "sarac"

 si nu aveam alta solutie. Eu as fi pus BA159, care costa 20 de bani.

Referitor la s?rmele folosite ?n sursele astea, cele de pe alimentarea din re?ea rezist? la 600Vcc, iar cele de pe ie?irile cu tensiuni mici la 300Vcc. Cine are nevoie de izola?ii la tensiuni superioare, poate ad?uga tuburi izolante peste sau caut? s?rme din monitoarele sau televizoarele cu tub catodic, acolo exist? ?ntre 1...30kVcc.
