220v AC to 12v DC

[renzo04]

hey anyone who has an idea how to construct a 220VAC to 12VDC  converter?

i was thinking to run my car audio system to my house instead. it needs to be high power to support the 3600watts amplifier.

any ideas please?thanks!

Sir gawa ka power supply yung may transformer primary is 220vac and 12vdc ang secondary, kaw na pumili kung anu rectifier mo bridge ba o center tap. taasan mo lang po current rating ng transformer mo and yung mga parts add a voltage regulator para sakto sa voltage ng car stereo mo. Meron po Schematics sa net search mo na lang

heto po pala post ni Gem. chop mo na lang po yung di mo kailangan

pinaka mabilis ATX 600watts.

[edtechph]

ok naman yung atx kaso ok lang ba yung load na ilalagay dyan?

[updated]

Amps = Watts / Volts

3600/12 = 300 Amps

[edtechph]

ang taas naman yata nyan? baka PMPO yang rating ng kanyang amp. yung tulad ng v12 model.

kapag RMS yan. malamang kapag full volume bingi lahat ng pasahero. Front seat lang yung likod speaker na

[renzo04]

rms po yan, pero d naman 3600 watts lahat nagagamit kc 400watts lng subwoofer ko.

meron n po ako 220VAC to 13.5VDC converter pero 4A lng ang rating.

my alam po b kau n circuit pra madag2 current?thanks!

Renzo, hook up an ammeter sa car battery mo and play the radio. Malaman mo ang current draw. based on that, gawa ka ng PS. may circuit ka dn sa isang thread for 6 amps. Kung 20 amps yan, apat na bypass transistor ang kailangan. Mahal ang 20A transformer ah! I have one here pero di bumaba sa P2k transformer lang. You can use the 12Amp sa deeco, dalawa kung 20 a and kailangan.

An alternative is to use a car battery na may auto charger like the one featured by Alexan. mayroon pa ako dito. Iwanan mo nakakabit. Call me or text me if you cannot find the kit anymore. 4 Amp charger lang ito pero auto off. The idea is that we will replenish spent power slowly over time.Di ka naman mag play yan 24/7, di ba?

another way is to use two or even 3 computer PS. Depende nga sa current need. Yung mataasang current sa 12V, brand new nasa P700 each. 3 will be P2100. Reasonable pa yun. may kaming kinoconect ng load sa 5V output to activate the regulation.

baka bus bar na ang ginagamit.

[RiDdLeR???]

heheheh baka yung 3600W eh PMPO yun at hindi rms watts.

[bravokilo]

kung 300 amps, kahit yung N50 na car batt will quickly drain. 50 amp/Hr yun and if the draw were 300, that is 6 times and the duration will be 60 mins/6 or 10 minutes. Game Over. Waaaaa
