    gran pequeño paso hacia arriba Paso hacia abajo convertidor. Un artículo bien hecho, fácil de armar. Es barato, pero la calidad es muy buena. Me permite ajustar mis voltios de 0 a 9 voltios en mi PSU de 9 a 24 voltios.

    Удобный блок питания, особенно в комплекте с корпусом, за такую стоимость. Даже с + доставкой. Думал что не положили две гайки для крепления корпуса винтами, но оказалось что отверстия в нижней части уже являются гайками. Всё работает и мне всё понравилось.

    Utile per avere una alimentatore a tensione variabile, per circuiti di prova o come dimmer. La misura di volt può essere claibrata per una corretta precisione dell'indicazione. La custodia in plexiglass arriva protetta. Io ho tolto la protezione in modo da vedere il solo display. Altrimenti togliere su tutti i componenti la pellicola. Montaggio facile. Useful for having a variable voltage power supply, for test circuits or as a dimmer. The volt measurement can be claibrated for correct indication accuracy. The plexiglass case arrives protected. I removed the protection to see only the display. Otherwise remove all the components on the film. Easy assembly.

    Als u handig shopt op Chinese sites kunt u voor vijftien euro alle onderdelen verzamelen voor het samenstellen van een regelbare gestabiliseerde voeding met een uitgangsspanning van 0 V tot 16,5 V en een uitgangsstroom van 2 A, met bovendien digitale metertjes voor spanning en stroom. Is dit een bruikbaar alternatief voor de dure laboratorium voedingen?

    The product works correctly. unfortunately the PCB is too big to enter the transparent container, probably a manufacturing defect. By checking the photos on the site the PCB has an extra portion that is difficult to remove without risk of breaking the PCB itself: certainly a manufacturing defect of this sample. Problem that Banggod solved promptly sending me, without charge, another copy

    ★ its a DIY kit, u need to fit all the things in casing. it took less than 5 minute... ★ Since 20volts is mentioned as Best input voltage range i used my old laptop Adapter 20v, 4.5A. Wow the setup is now complete. Calibrate it if needed ★ This tiny device Works perfectly, we can get desired output colt as per our need. i main use 2.8 v, 3.3v, 4.5v, 6v, 9v, 12v, 14.5v ★ i set 14.5v as output and charged my 12v 5Ah battery ★ its peak current is 3A. but using devices upto 2 to 2.5 Amps is a good choice

    The output voltage range 0-16.5V is perfect, measures the voltage (can be calibrated fine) and current, what else do you want for $5? The acrylic case is very creative puzzle like solution :) Mine is a bit different than on previous buyer and BG pictures, additional slot are cut for the display's connector soldering and for two jumper like pads. I think it is for the less tension inside the case. Although I received the item in an uninjured condition, I would highly recommend the seller to put additional foam INSIDE the package close to the display, because other parts can easily damage it during transportation.

    Bastante bueno para el precio que tiene. Con 12V llega a un máximo de 11, así que si se quiere 12V o más hay que usar una fuente con más voltaje. La pantalla muestra un voltaje más bajo del que realmente proporciona, así que hay que tenerlo en cuenta, pero después se mantiene bastante estable. La medida de la corriente es bastante fiable.

    It took me 3 minutes to build the case and 1 minute to calibrate it ... After that i played with the voltage and realized that voltage values are not so accurate (there is a 0,07 mean value difference from real voltage .... but its normal i think for this great price ! I connected a power diode at positive output pole, i adjusted voltage at 14,5 volts and connected to a pair of 12 volt 7,2 Ah lead acid battery ! Everything worked fine ! Charging process started at once with a starting current of about 1,4 A and as charging was going on the current dropped to 0,26 A on a charged battery voltage indication of 13,6 Volts ... Not bad at all !!! And temperature was fairly OK ... not heat to make me worry about So i think i m gonna order another one ! Great item at a great price !

    5 minutes to assemble it. Very easy, just plug a Laptop power supply to the source and you will not have any problem to select the desired output voltage. Good feature the amp meter on the display
