XL4015 5A DC-DC Step Down Adjustable Power Supply Buck Module LED

After some tinkering with the 4 devices I received I was able to get them all working, just make sure to turn the pot around many times before attempting to use.

Works fine

All four work perfectly. I’m impressed with their performance, there’s a little voltage drop under load but that’s to be expected and easy to compensate for.

A heat sink was included for each circuit board but there was no instructions on where to put it.

Used this to lower voltage from a 24v power supply to 9v for a motor in a Halloween prop. Works great!

product arrived in sealed packages. works great. although i did not receive the mounting screws.

Works perfect for my purpose. I want to lower the voltage to the LEDs to get a warmer light as it dims. Wonderful.

Had no issues with them. They don’t get too hot. The heat sinks may look flimsy but they do their job.

Worked for me. Used in a diy powered speaker.

With a 2 amp load there is little to no heat generated. Voltage is very stable with even a fluxuating input voltage.
