    Kind Attn: Drok Power supplies

    Dear sir/madam, We are using a DROK power supply in one of the university funded projects. There is no name printed on the board, except DROK. The requirement is we need a 12V to 9V buck regulator for the project. We tested the board by providing a regulated DC voltage of +12V, but it seems I do get the same voltage across the output. Kindly advise as to how to use the board, since there seems to be some trimpots on the board for voltage adjustments also.

    Dear Drok Engineers. I had sent my query to drok, via service@droking.com, on 19th June, with board pictures. I did not receive any response as of now.
