U can test start to half strip or single led, otherwise u have to use higher transformer 60v

Well done! It is better to add a DVM (digital voltmeter) to your design.

[@gundogankazanc9241]

Any white led draws 20mA maximum but this ps you build, can give 45 mA current at 34V (ideally 24Vac transformer gives 24*1.41=33.8Vdc) output and with totally 660 ohm serial resistors that this current is harmful for ordinary single led.

I think your slm videos are educational. Thank you. I have a question. I don't want to spend on my cordless drill and buy a new adapter or tarsformer. It's expensive. Can I convert my 12V, 2A adapter to 14.6V and 20A, I need your information, thanks

[@gundogankazanc9241]

It's impossible. The power of your present PS is 12*2=24W. Whereas you ask 14*20=280W. It looks like to hope a child 5 years old to carry a 100kg weight. You should buy a more powerful PS. Sorry, this section is Turkish: Sonradan farkettim, soru soranın adı Türk olduğunu kanıtlıyordu. Herneyse, yukarıdaki lafın özeti 3 kuruşa 5 köfte olmaz. Sen herhangi bir güç kaynağının akımını veya gerilimini artırıp azaltabilirsin ama gücünü yükseltme olanağın yok.

[@gundogankazanc9241]

@@asifshahsyed422 sure. that resistors limits load current but under constant voltage. according to differences of the work or test, you can use vary values. if the R is big so the current goes lower and R is less, current is much more than first one. i always prefer less current not to break down something

so i understand that the voltage range is 3to 32v? how can i make with higher voltage range? what about amp? how i control the current so is this setup can work with powerful led 30w or higher? i need to build one that i can use it to test single leds or strip with any voltage upto 100v for example and i will install voltmeter and amp meter to know the voltage and current suitable for the led is it possible?

[@عمارةحامدي-ذ7غ]

Have a nice day Mr. Tariq. Honestly, among the videos I watched on LED testers, it was your LED tester that I chose to do. But the transformer I bought is 18-0-18 Volts and not like your 12-0-12 Volts transformer. Question: do I always keep the same values -capacitors (50V, 1000 microfarads)? - the 2 resistors (2×330 ohm)? Thank you to answer me to start testing my LED.

Increase resistors to around 420 ohm and better to use 63v capacitor

[@عمارةحامدي-ذ7غ]

Good evening Mr. Tariq Thank you, I have already built an LED tester of this type, it works properly, however I still have a few questions: 1- Is it possible to get rid of the capacitor? If not, what is its role in this LED test? 2- Since we used a diode bridge which rectifies the alternating current into direct current, why then use a transformer since the diode bridge is enough when we can weld two diacs between the positive and negative terminals of the diode bridge. Thank you.

Capacitor is a filter capacitor to smoothing the DC voltage.
