pa help naman po mga sir,, anu po ung ic para maging variable ung power supply, tanung narin po ako kung anong site ko mababasa ung power supply na may +24V tsaka -24V?

ty poh mga sir

Ang alam ko positive output lang yung sa lm317t.

Yung bang +24v at -24v
di ba pwede mag dual power supply ka using 12-0-12 xformer

Pwede yata gamitin yung lm317 saka lm337 in combo, 317 sa positive tapos 337 sa negative. Alam ko 1.5 A sa spec nya. Kuha ka na lang ng datasheet ng LM337 sa net, sa datasheet nya meron na dun application sample ng component na ito.

Me alam ako na site ng mga datasheet ng components. Nabanggit na rin yata dito kaso sa ibang thread.

Variable VR mga ito. Commonly nakakabit sa center tapped na transformer ang configuration tapos diskarte na lang pagkabit sa potentiometer(stereo o dual) para ma-attain yung pagsabay ng pag vary ng voltage nila.

May schematic ako dati nyan kaso nawala, ang nasa akin ngayon lm317t at lm337 kaso fix yung voltage, ito baka makatulong sayo may konting info jan.

pwede mo ibase dito

modify mo na lang yung gagawin mo

Depends on your requirement bro, kung 1A lang maximum kelangan mo ,I think sufficient ung binigay nila.

If not, then just post again para ma-modify ung mga replies .tnks.

all capacitors are for filtering...

palitan mo ng dual gang na 5k pot yong r2 at r4 para maging adjustable.

geh po mga sir tatry ko gawin ung binigay niyo sakin sa xmas break ^_^
