    A good DC-DC converter. I use it to regulate the output power of a LED power supply for my hobby projects. The filter capacitor for the trimmer potentiometer has a dedicated spot on the PCB. This is not common for some of these boards which can be annoying when you want to replace the trimmers to some other potmeters. The solders look nice and clean. Heatsink goes hot when larger power is used, so it is a good idea to use some fan to keep it cool.

    Este Step Down tiene buena calidad funciona según lo especificado ya le hice pruebas y funciona muy bien, recomiendo mucho este producto. Los voltajes como el amperaje llega ademas tiene buena dicipación de calor, es bastante conpacto y puede servir de mucha ayuda como fuente de alimentacion para proyectos electronicos como por ejemplo arduino donde se requiere de un voltaje y amperaje constante.

    Der Step-Down Converter lässt keine Wünsche übrig! Die Ausgangsspannung und die Ampere-Abgabe lassen sich über einen Poti einstellen und die Kühlkörper sorgen für die nötige Kühlung. Die Ausmaße sind kleiner als ich dachte - somit lässt sich das Bauteil bestens verbauen!

    Package is very well protected. I use it to step down 6S battery to charge other batteries with EMAX charger. I set output voltage to 18V and when charging, the alim output jump from 18V to 22-23 and back ! nothing but stable !! EMAX charger has a max input at 18V and it didn't warn for over voltage input so... finger crossed, look like ok

    Преобразователь доставили меньше чем за месяц до порога и вручили на руки. Преобразователь работает, замечаний нет. Не везде смыт флюс, но это не проблема. Более подробно пока не тестировал. Товар за такие деньги понравился, можно брать.

    Купил по акции. Преобразователь стоит своих денег. Обязательно проверьте хорошо ли затянуты элементы к радиаторам. Заменил потенциометры.

    It works fantastically, the trimmers are somewhat uncomfortable and the power switch is somewhat complicated to activate, but it has a very good efficiency and a good range of voltage and amperage reduction. tested with two lithium-ion batteries with 3.8v each, to use a 7.6v serial sum, reducing to stable 5v (Mark 4.8 because I need to calibrate that Voltmeter-Ammeter, tested with common multimeter).
