    I bought 3 pre-order kits. They now cost less. I was thinking of using them to feed small projects to replace batteries. I think it can be fed with voltages below 24 Vac. I did a little test. Without load: Vac = 19,6 Volt --- Vcc out = 21,2 Volt With load (8 ohm and Vcc = 8 Volt then 1 A) Vac = 18,86 Volt --- Vcc (without load) = 8,04 Volt --- Vcc (with load) = 7,98 Volt. Note: The maximum current before the protection is: 8.72Volt / 8ohm = 1.09 Amper. I also tried with a lower power supply. Without

    useful and versatile power supply Kit from Hiland. it use the classic LM317 voltage regulator IC. the pcb is very well made. please take care that the heatsink it is not included. good practice kit. suggested kit alimentatore con il classico regolatore Lm317; il PCB è ben fatto. Attenzione che il dissipatore non è incluso. Kit utile e consigliato per fare pratica di saldatura. consigliato

    A useful and easy to assemble source with the well-known LM317 integrated circuit, voltage regulation between 0-30V and, surprise, current setting between 0-1A. Very useful for DIY projects with consumption up to 1A. You can use the cooling assembly made of an aluminum radiator and fan (24V) found on banggood.com. Excellent Banggood!

    mounted all parts on pcb, tested on 24ac input.. posible to control V and I with potentiometer but the output voltage is max 6,5V ?? some problem with transistors or IC. will be easy to repair if producer attached el. drawing for pcb. lm317 get hot on o,5A load, need good bigest Radiator

    Stavebnice lineárního regulovatelného zdroej 0-30V 0-1A. Perfektně vyrobena deska plošných spojů. Otvory pro osazení součástek jsou prokoveny a upraveny pro snadné pájení. Koupil jsem dva kusy - vše OK. Uvítal bych dodání schéma pro snadnější hledání závady.

    I got all the resistors and small capacitors in and ready to solder and then I remembered what one U-Tuber said "test test and retest at any point that will provide useful results it is much easier to test early than to troubleshoot once it is built" so I pulled all the components out and tested them so now I can restart my build.

    Arrived in good conditions. Assembled (to easy actually) and testing whith old transformer 14.4 v single. Looks like work properly. Waiting to arrive new double transformer 12-0-12v AC 30w. Order new kitt to make one home made power bench supply.

    i'm a beginner and it took me about 1h to solder and verify this kit. (including veryfing resistor value and sorting them ). As i had not an AC 24V input, i tried with DC. Values are not really as advertised but this could be related to the absence of heatsink ! (max voltage was 18V with 24v dc input) - i may need to reinspect everything. I first though the led was not working but if you read the description, it lights up only when the current limit is reached ! I did'n pay attention to the

    Ok, semble conforme, pas encore montée ni testée, les potars semblent très très cheap !
