🔒 Closed Patolong po paano gumawa ng 12v power suply using 18 to 20 v tranpormer output
- Thread starter armiah13

sa AC in diyan mo ilagay ang output ng transformer mo na 18-20 volts
kung gusto mo tataas ang ampere niyan mag parallel ka lang ng 3-4 transistor na 2N3055
kailangang malagay sa heatsink si 2N3055
Hindi po.... power suply po ..

oo power suppy nga yan
Ahm dko alam kong paano mag paralil po ng transistor po..

diba ang transistor ay may tatlong paa (base, collector, emitter ) lahat ng base ikabit mo ,lahat ng collector ganun din pati ang emitter
Boss alam mo kong paano gagawa ng charger sa malalaki na battery ?
Ahm sa plagay nyo po ilang amper kaya tong transpormer na ito. Malaki kasi ito ehh.. Bxta 18v ang outpot nya
Ahh cge cge po salamt po sa tolong

Kung hindi naman ganun kalaki power requirements, puede rin ito..
The resisitor under the LM317T is 240 Ohms, The resistor that is going to ground is 2K OHM, The Cap to the right is 47uf 35v, And the cap next to the diodes (bridge) is 4700uf 35v. Use 1N4001 rectifier diodes.
LM317T specs:
3 pin TO220 package
DC out 1.2v - 37v [adjustable]
1.5 ampere rating
Gamit ka lang breadboard PCB puede na yan, throughole 1 sided lang para sa small circuit kagaya niyan.

ok po salamt
ok po salamt po.. ahm pag aralan kopayan kasi nalilito kasi ako... hndi pa kasi ako maronong bomasa ng mga ganyan

Basic lang yan boss.
eto lang mga kaylangan mo!
~4Pcs 2amp diode
~10-15k ohms na Resistor
~Electrolytic Capacitor with capacitance of 25v and 3000 microfarad.
~LED indicator with 3-5k resistor
~switch (optional)
~fuse (optional)
.
Pero pwede rin dalawa ang output voltage na 12v-18v gamit ka potentiometer.

pwede yang sinasabi mo tol kong mababa lang ang kailangan pero kong gagamitin sa audio amp. baka masunog ang potentiometer na sinasabi moBasic lang yan boss.

Hindi boss meron ding desired na resistance depende sa taas ng voltage.
.
Nag aasemble kasi kami ng mga sound system kaya medyo expert na ko
Ang variable Resistor ang magiging pinaka switch mo kung ano output voltage ang gagamitin mo
okey .. basta sa akin pag ganyang sitwasyon hindi talaga ako gugamit ng potentiometer na pang dropping sa B+ line lalo na high current ang kailanganHindi boss meron ding desired na resistance depende sa taas ng voltage.

ah yes sir pag B+ talaga malakas ang voltage nya kaya Hot part ang tawag sa kanya
iba kasi ang hot sa amin boss primary line yan at cold naman ang secondary line pag sa tv. naman dalawang klase ang HOT primary line , and horizontal output transformerah yes sir pag B+ talaga malakas ang voltage nya kaya Hot part ang tawag sa kanya
