💡 Valefod LM2596 DC to DC Voltage Regulator 3 Pack - Efficient Buck Converter with LED Display Review

Wow what a great product. The keys don't regulate the tension as one might assume. You simply switch the displayed voltage, whether input or output. Use a tiny potentiometer to adjust the V output. It takes a few turns before you see a voltage drop. Good product. Very difficult. Works perfectly.

These devices have allowed me to install 12V quieter fans in my 24V powered 3D printer They were very easy to install, built in with screw terminals. A set screw makes it easy to set the output voltage, and the display makes it easy to see what voltage is going to the fans. Great product so far.

I'm downgrading from 12 to 14 volts to 5 volts. The readings make it unnecessary to use a multimeter, which is good because I didn't want to spend a lot on my little car project. As far as I know, these little guys walk cool. And from what I've read about this type of regulator (buck converter) they are as efficient as can be. That means no excessive power consumption.

Stable voltage at different temperatures. Needed in the car under the hood or in the car. A clamping zener diode has been added to the output to protect devices that cannot operate on 12+VDC. I have installed 6.5vdc units for stable fuel level control for older cars. These blocks hit the input voltage when something happens. So the fixing zener diode. I use 7.5 volts and add a pico fuse to the input so it outputs 0.5 amps.

I bought these to power a couple of promotional LCD video players that I've opened up for Halloween decorations. The first failed to provide stable voltage by sending two words excellent. That's why I bought three. Learn more about what failed. Initially it turned on and output 5V DC. did the setting for 3.7vdc but then it dropped to 1.5vdc. I adjusted the voltage, but the maximum value was 2.5 VDC. any load renders the device unusable. By any load I mean LED and resistor. 2 out of 3 is not…

I purchased these converters for a 24V to 12V fan conversion I was doing on my 3D printer and they far exceeded my expectations. They are easy to use and work well for my application. My only criticism is that there were no instructions included. Not that you really need instructions to plug them in and use them right away, but they do have a programming procedure if you want to fine-tune your voltage settings. I found this procedure online and it was easy to follow and follow. The quality is…

I was hesitant to buy this set of 3 because I could get 8 without a display for the same price. I ended up buying 2 with no display but they were dead on arrival so I returned them. I decided to try this product as I found it convenient that I don't have to take out my multimeter to set it up. I'm very glad I did! Usage: The left button toggles the display on and off. The right button toggles the display between input voltage and output voltage. There are displays that show what voltage you are
