Adjustable DC power supply, 4-30V AC/DC input, 1.5-27V DC output


Used for powering the amp and volt meters.

Input: 4-30V AC/DC
Output: 1.5-27V DC (adjustable)

      With each power supply we also include:

      (4) 1/4" Nylon Standoffs, 4-40 Thread
      (4) 4-40 Nylon Screws
      (4) 4-40 Nylon Nuts (for those who do not wish to thread and tap the back plate)

          Nylon standoffs and screws are the best way to keep the leads on the bottom of the power supply circuit board from shorting out against the back plate (destroying the power supply and possibly the meter as well). 

          For installation and wiring instructions, see our Control Panel (Part 1) and Control Panel (Part 2) build guides.

          Separate power supplies are required for the meters as the volt meter has one of the AC inputs tied to the DC ground. For more information see the 'How it works' section of our volt and amp meter wiring instructions. If replacing a meter that was damaged due to incorrect wiring, we recommend that the power supply be replaced at the same time as it may have also been damaged.
