I try to modify a PSU of 12V 12,5A that actually deliver 13,7V in this way to obtain approximately 16V so I can charge with it a 12V 92A AGM batterybrOn my PSU it have on the PCB 2 resistors of 2,2KbrI used a 220R resistor and a B5K but it's ticking, hardly starts for 2-3 seconds and stops, delivering a maximum of 9VbrAny advice, what values to use for the desired 16V as output?

Give me diagram please Comment from : Taufiq Budiman |

I did same but not getting exactly, perfect from 9-24 v, but fluctuating below 9 v Any help ? Thanks in advance Comment from : Harry |

My power supply is 12V 5A 60W Can I also do this method ? Comment from : Kamal Gunarathna |

If you reduce the voltage, can the internals handle any corresponding increase in current?brSimilar questions exist if you increase the voltage (beyond the previously fixed voltage) will the components get fried?brMy serious advise if you want a variable voltage supply BUY ONE, unless you happen to be a very highly skilled/competent in power circuitry and know exactly what you are doing! I really admire people who play with electronics but there are are always dangers - fires explosions and electrocution which can be fatal! The rusts massively increase with decreasing skill level Comment from : kychemclass |

Very excellent, and these are suitable for supplying and reducing the intensity of lighting for LED lamps Comment from : Electro Geek |

Oder man nimmt gleich einen Dimmer als simpelste Platine und setzt paar passende Leistungs- Triacs dazu ohne alles zerlegen zu müssen, plus 4 Brücken Gleichspannungswandler bis zB 600 V, den passenden Elko über 220 V Plus 4x60 V , intelligente Z-DIodenschaltung mit IGBT statt der Schwebenden LED Birnen mit noch schnellerem Kurzschluß Die herunter geregelte Spannung kann man nochmals per LM und dahintergesetzten Sperrschicht - Mosfet feinregelnbrbrBeim Laptop muß der Trafos schon noch zusätzliche Anforderungen erfüllen brBei Akkus auch noch eine geeignete LadeautomatikbrbrDeshalb die SMPS - Trafos und auch zusätzliche Sicherheitsregelschaltung bei Computernetzteilen ,die dort nicht zum Spaß da sind Comment from : Naturix |

it is better to change output capacitor to higher voltage Comment from : jammm khaei |
 |
have to check output capacitor voltage!!brusually only 16V on 12V supply, so change to 35V for breliable/b 16V outputpoor quality capacitors may go "poof" if used at maximum voltage for any longer time! Comment from : Lohi Karhu |

Usefull info technically, thanks full 🎉🎉🎉🎉 Comment from : Adrian Engineers |

You might find some PSU will start switching on and of if the voltage goes too low This is because the output voltage from the transformer to the pulse width modulation controller chip drops too low, and you get that clicking on an off from the PSU Comment from : P F |

Good job mr zafar Comment from : Manny Magoe |

ماشاء عمل ممتاز ، تشكر Comment from : ammar benzouai |

Keep in mind that no matter what voltage you set, it's maximum output is 156W That 21W automotive lamp will cause the power supply to overheat and it will either thermal shutdown or burn up at that load It's the switching transistor that would burn and thermal shutdown will only happen if that feature is built-in with a temp sensor on the heatsink That's a pretty big supply for only 12V/13A [156W] You can get small wall warts that put out 3A@12V and small laptop like/style power supplies that put out 10A@12V Comment from : DrHarryT |

Ustam emeklerine sağlık benim sormak istediğim belki bazı arkadaşlar içinde faydalı olur bu smps adaptörler çok bulunuyor ve tahminim herkese bir tane vardır benim isteğim ustam aynı 12v 5 yada 10 AMP lik bu trafolarda senin yaptığın şekilde aynı direnç ve pot ile yapailirmi yoksa malzemeler değişecek mi birde ustam buna akım (AMP) ayarida yapıp bir vedo daha paylaşırsan dadından yenmez tekrar emeklerine yüreğine sağlık ustam ❤️👍 Comment from : SINAN YC |
