    Works as specified if you stay in the limits. Just a little warning: during my tests, I lowered the input voltage and under 3.5V, the circuit doesn't cut but becomes crazy and the output (that was set to 15V with the pot.) jumps to 40V with no load. With a 2k resistor at the output, it only goes to 30V. Of course, this is under the specified minimum voltage, but for solar applications, how can you guarantee that the input voltage will not be there? So when it says "Module Suitable For Solar Panel" I'm suspicious. If you really want to use it like that, you could add a small circuit between the solar panels and the converter to cut it if the voltage drops under the minimum 3.8V or clamp the output with a zener (there's no voltage rating on the output capacitor so that kind of overvoltage could damage it if it is not designed to handle 40V) Also the problem with that kind of circuit is that if you try to extract too much current from a solar cell, its voltage drops, but then the converter will try to get even more current to keep it's output and the input voltage drops even more... So you also have to add a circuit that limits the output current when the input voltage drops. Conclusion: good circuit if you use it properly but not really appropriate for solar panels despite what it says in the title.

    سيتم استخدامها في المستقبل مع إمدادات طاقة الكمبيوتر القديمة للفولطية المتغيرة. لقد اختبرته بمصدر طاقة و قمت بقياس جهد الإخراج وكانت المدخلات 7.2 فولت. لقد استخدمت الخرج في الفولتات أكثر من 25 فولت نزولاً إلى 1.5 فولت. جهاز تشذيب فولطية الخرج حساس للغاية (10 مقياس قدرة دوران) بحيث يمكن ضبط الفولطية الدقيقة بسهولة. يجب أن يكون فولطية الدخل 5 فولت أو أعلى للخرج الثابت.

    هذا لطيف جداً

    I ordered three of these modules. I had never used them before, so I hooked them up to a basic adjustable power supply and measured the output while I made adjustments to the trimpot. I was having problems with the output voltage on the first one I tested, where it wouldn't go below 9.5V, even with a 5V input (I needed 3.3V). The step-up still seemed to work fine. I tried to figure out which component failed, but I never did. I even removed the trimpot for testing and resoldered a couple of surface mount resistors. I tested the second one, and it worked fine. I tested the third one, and it worked fine, but while I was adjusting the trimpot, I encountered the same problem and it jumped up to 9.5 V. I think this was probably due to an error on my part. I think that my alligator clip probably slipped and shorted something out. This also led me to believe that I probably killed the first one in the same manner. My advice is to be very careful when using this module, and to solder wires in place before testing. In my case, I feel that the error was on my part, and I will be ordering some more in the future, since they are inexpensive. Also, the circuit boards on all of mine were misprinted as part DSN600AUD instead of DSN6000AUD. Other than that, they are identical to the one in the picture.

    خطوة أعلى خطوة أسفل تيار مستمر إلى تغيير التيار المستمر. وهي تعمل بشكل جيد بالنسبة للأحمال الصغيرة مثل أجهزة التهوية أو محركات التيار المستمر الصغيرة أو غيرها من الأجهزة الإلكترونية. أحب ذلك لمشاريعي الخاصة.

    With a 12V power supply I achieve 1.75V to 47.5V output range, pretty good for the size and can easily be incorporeted inside any electronic project

    Device arrived set to 20V output. Left turn Driving a small 19V load from a USB power bank is no problem. If a more powerful source is used and the load uses more power, the temperature can rise quickly. Keep an eye on the power throughput.

    Converters work as described. Good price.

    All worked normally.

    They work great, I was impressed by the resolution of the trimpot and consistency of the voltage output. They have a wide range of input and output voltages and the current is enough for many applications.
