bili ka na lang ng power supply ng computer cgurado ako mas mura yun. Cguro yung PSU na rated na 450 watts meron yung 15A-12V power supply. Gagamitin mo ba to sa audio amp?

Depende sa application mo? Sa Amp ba or sa power electronics?
Yup pwede yung sa PC power supply, kaso kung may inductive load I prefer Transformer type. :)

Napa isip lang ako kung gano kaya kalaki yung transformer nito para na handle yung 12V-15A. Cguro malaki laki din yun heheheheh.

kung gagamit ka ng simple linear power supply circuit, medyo magkakaproblema ka sa pagcontrol ng init nung transistor. Msyadong mainit for 15Amp rating. chaka malaking transformer ang gagamitin mo. Simple ang circuit pero malaki.

The best is hanap ka ng switch-mode power supply circuit. yung simple lang, flyback lang.

kung sa charging ng 12volts battery mo lang gagamitin eh bili ka na lang ng 12volts na center tap. tapos ang gawin mong rectification eh full wave. lagyan mo na lang ng magandang heatsink yung diode mo...

proportional sa power ang size ng transformer ... 12 x 15 = 180 watts ... approximately singlaki ng 200 watts na transformer na makikita mo sa mga hardware

lerx, baka 12.5V. Kung 125V, that is too high.

get an atx pc psu, even generics will have easy time delivering 15amps.....doing this supply using an EI traffo and linear regulator is going to be hard work, and inefficient.......:)

sino meron na 12v output power supply pang halogen na 12v/50w para dun sa lighting ng sound system. 220 input di kasi tatagal yung linear sa init. yung parang flower yung lumalabas na ilaw.
