This is a nice little power module with an adjustable voltage and a high current output. It supports both DC and AC as an input. It drops voltage down from 40V!

  • Input: DC3V-40V DC or AC 2~30V
  • Output: 3~40V DC linear adjustable
  • Power: 15 Watt max
  • Current: 1.5A, 2.5A peak (need a bigger heat sink for higher current output)
  • Size: 53mmx 41.5mm x 15mm
Note: Input must be at least 1.5V higher than the output for stable output
Example: Input DC 30V, Output is 3V~28.5V adjustable (15W max)
Average rating 10 out of 10 ( based on 1 review )

got this little piece from amazon, wondering how to adjust the dc output, any user manual? tks Reply by support: There is a small potentiometer (VR) on board. Just use a small screw driver to twist it to make volt adjustment
