    Very good, ship with anti-static bag. Product was packed properly. Line regulation is good, tested with 5-30v in input, and 2A load. Suitable for led, or no analog device without filter. Current limitation work fine. I'm bit disappointed on capacitor choice. They are 105degree ones, but only 35V. 50v ones would have allowed a better lifespan.

    Great product. I used it to build a bench power supply with 2 variable channels and it works fine.

    Nice and compact... Voltage is very stable.. Temperature isn't an issue.

    this circuit is very well made, I connect to it a 12Vdc power supply and the output arise till 30 Vdc. 2 trimmers are dedicated to the output voltage and current limit adjustment. very versatile and very good value for money. il circuito è fatto molto bene, l'ho connesso ad un alimentatore da 12Vdc e l'uscita è regolabile sino a 30Vdc. ci sono 2 trimmer per regolare la tesnione di uscita e la corrente di uscita. molto versatile e ottimo valore prezzo prestazioni

    this converter can help you in solving many power supply problems. it is able to increase or decrese the voltage at its output terminal compared to the input voltage. the output is quite stable with the load change and the multi turns trims help you in adjusting the output voltage level and the max output current as per your needs. One of the thermal pad below the MOSFET was slightly out of position, but I solved this issue very quickly - check the pads before power up the circuit. good value for
