    Order on time and well packaged. I tested it with my countertop source and put a multimeter on the exit and set it for a low tension outlet. It didn't warm up. But I would recommend the utmost care not to reverse the entry tensions because it can give rise to problems. Very small and very compact. I recommend this article. Look at the photos and like.

    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

    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.

    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 money. suggested questo convertiore permette di aumentare o diminuire la tensione in uscita rispetto al valore della tensione di ingresso. la tensione di uscita è stabile rispetto alle variazioni della corrente del carico. i trim multigiri permettono una buona regolazione della tensione e della massima corrente di uscita. Un MOSFET aveva il pad termico leggermente fuori posto, ma ho risolto velocemente il problema. suggerisco un controllo dei pad termici prima di dare tensione al circuito ottimo valore per il prezzo. suggerito

    Works great and it doesnt heat up. Used a 12V SMPS with this and can only reach 1.1V - 29V. I hoped to reach 30V but this has the best value for buck boost converters here. 5 stars!
