Yizhet Regolatore di Tensione Convertitore Buck DC-DC Step Down Modulo 3.2-40V a 1.25-35V Ajustable Fuente de Alimentación 10 Pezzi

don't get upset if it takes about 4 complete turns before it responds. It is a 10 turn adjustment and gives you an accurate setting. I have an alarm system that operates on 9 volts so to run it on a 12 volt car battery, I adjusted this to 9 volts and the system works great. I also installed one in my wireless door bell that runs on 4.5 volts but the AAA batteries kept running down. Now I use a 9 volt power pack to power this unit and drop the 9 volts to 4.5

Review for: Yizhet 10 Pack LM2596S Buck Converter DC to DC Converter High Efficiency Voltage Regulator 3.0-40V to 1.5-35V Buck Converter Adjustable Power Supply ModuleTested and they work good. This is my first go as using this kind of voltage regulator, in the past I have only used 78XX series regulators that waste lots of power as heat. Not so with these! Tested running 5 volts into a 5 ohm resistor, 25 or so volts input. After several minutes there was very little heat coming from the regulator board, lots of heat from the load resistor. Turning the voltage down to about 10V and up to 35V I noted the current draw changed, always less than the 1 amp output into the resistor.Very happy with these regulators, both from testing and my first application.My first application is a LED light dimmer. I obtained a solar power light string that runs on about 3 volts. Was not happy with the solar power supply, mostly due to the stupid flashing modes, but also the high frequency flashing of the LEDs when set to stead on. I cut the solar battery off and made a light dimmer from one of these modules. I added a 220 ohm resistor and 1K linear variable resistor, in series, across the two terminals of the on board trimmer that are closest to the center of the board. Adjusted the trimmer for maximum of 3.4 volts output. The added variable resistor is now a nice light dimmer running from 3.4 to 2.0 volts - maximum power my LED bulbs say they can use, to zero light output. Put it into a plastic project box using double sided tape to mount the board, and attached a 12V cigarette lighter plug. I included a blocking diode on the input just in case, since I had enough voltage to work with. Works great.

Schnelle Lieferung, guter Preis, funktioniert einwandfrei!! Klare Kaufempfehlung!!

Works good. Good for tinkering, but would appreciate screw terminals instead of having to solder wires to it.

und lassen sich mit dem Präzisionstrimmer gut einstellen. Die Spannung stimmt auch nach einer Woche noch mit der ursprünglich eingestellten überein. Eingangsspannung ist bei meiner Anwendung ca. 24V , Ausgangsspannung 3.3V (für einen ESP32). Kauf-Empfehlung.
