Description of 🔌 10pcs MakerHawk LM2596 DC-DC Buck Converter: High Efficiency Step Down Voltage Regulator, 3.2-46V to 1.25-35V, 3A Adjustable Power Supply Module

Input: DC 3.2V to 46V (The input voltage must be more than 1.5V higher than the output voltage. Can not boost);. Output: DC 1.25V to 35V voltage continuously adjustable, maximum output current is 3A;. High Precision: 36 u thickening circuit boards, high-Q inductance with LED indicator output;. Steps: connect to power source, adjust the swirl button on the blue potentiometer and monitor voltage with multimeter to get the needed voltage,clockwise to step up voltage and counterclockwise to step down voltage. (Factory default stays a high voltage, you need to contrarotate about 7-8 circles before the voltage starts ramping down, 1 circle means +/- 1V);. Note: This is a buck module. The input and output interface can not be reversed. The input voltage must be higher than the output voltage.The input and output interface can not be reversed.Keep it under 2.5 A and use the heat sink when working for long hours.

Good product good seller

Item received quickly as usual. Small devices work like champions. Connected to a 36v battery and lowered the voltage to 5v so I could wire up a bunch of LEDs. Perfect

Pros
  • Certified
Cons
  • Could have chosen a newer model

You really can't go wrong with anything more than a dollar to dollar converter!

You really can't go wrong with a just over a dollar for a dollar converter! I've only needed a few for a few projects, but over time I'll find a use for the rest. They work very well. I only tested them for my projects, so I didn't exceed 15V input and 12V output, but they didn't get more than 3 or 4 degrees Fahrenheit. It's easy to set the exact tension you want. Out of 10 I had 1 who didn't want to work. I would definitely recommend her. Also a very small area.

Pros
  • An Absolute Legend
Cons
  • Periodicity

Works as it should: Power accessory

All 10 are individually boxed. They work as expected. Be sure to set the voltage before connecting the load. According to the data sheet, the maximum diode current is 3 amps. If you plan to run this above 2 amps I would consider replacing the diode with one with a higher current rating and possibly less voltage drop. The included SS34 gets pretty hot at 2.5 amps. We also recommend buying a small heatsink for the ESC. I would like the vendor to include it as some other converters on the market…

Pros
  • Ideal for outdoor activities
Cons
  • Operating speed

Normal quality, works well

The bottom of all circuit boards is dirty (first photo). Upon delivery, one of the devices in the bag was broken (second photo). Generally not the best quality. Although the units work fine. I recommend turning the screw fully counterclockwise before connecting the power supply. They are set at the factory to the highest voltage level. If you are using a low current power supply, plugging in that power supply will saturate the power supply. After connecting the power supply, turn the screw…

Pros
  • Constant test results
Cons
  • boring packaging

Bad batch?: Power supply accessory

I used a very good desktop power supply and no matter what voltage I put in the device (I tried from 5V to 30V) the output voltage only dropped to 3.5 to regulate 4.1 V. Then I opened and tested three more with the same result. I looked at the datasheet and found that there is a voltage divider element that sets the output voltage, so I started researching things and they didn't match. I unsoldered an adjustable trimmer and underneath was a small SMD resistor between two legs. I removed that…

Pros
  • Very impressive
Cons
  • Negative impression
