meris ripple ditto na grejacu

 

ako postujes detalj kako si vezao katodu , mozda mi jos nesto padne na pamet za merenje

usput - i taj bi bio bolji da se insertuje cap multiplier u pozitivnu granu

jbga, bez muke nema nauke

btw. zato sam ja i krenuo da razvijam nesto sto je bolje od Colemana ........ bar iste performanse a ne trebaju toliki zahtevi

mada on malo i preteruje sa savetima za predfiltraciju

I ja zainteresovan. 4p1l PSE. Želja.

ja ovde nista ne kontam :P

bez ukljucenog napajanja na osciloskopu dobijam 5.5mV AC

sa ukljucenim Coleman regulatorom nesto se malo vise poveca na 6.3mV

pronasao na velikom DIY sta Coleman kaze o merenju AC ripple-a na njegovom regulatoru

Yes, the voltage that you measured (0.000V rms) is expected - there will be less than 1mV of ripple on the filament with a Coleman regulator, even at 3.5A. 

sto znaci dzaba sam krecio, nista ja tu necu videti
