I have just bought two but yet to try them out. They are available from multiple sources but try mini-in-the-box and light-in-the-box. Here's a link for the former: http://www.miniinthebox.com/adjustable-power-dc-dc-module-3-a-step-down-voltage-regulator-module_p1654675.html they also have units incorporating a voltage display meter. Caution the stated amp output rating is max WITH A SUITABLE HEATSINK- possibly more than one (above and below the board)!! Even then it may not be achieveable across the whole voltage range without exceeding the SOA of the unit - use caution.Bob The Bloggerhttps://www.blogger.com/profile/10718200071540788914noreply@blogger.com
