Handmade DC7 Guitar Effects Pedal Power Supply

True Isolated Design
This PSU features fully isolated outputs, where both the positive and negative terminals of each channel are independently isolated. This ensures no electrical connection between any channels, minimizing ground loop interference.

How to Verify Isolation
Use a multimeter to test continuity between:

• Positive terminals of different channels
• Negative terminals of different channels
  If negatives are connected, the PSU is not truly isolated.

Channel Specifications

• Channels 1–4: Fixed 9V output.
• Channels 5–6: Customizable (select one per channel):
• • 9V/500mA
  • 12V/400mA
  • 18V/250mA
• Channel 7: Fixed 12V output (directly linked to the 12V IN port).

⚠ Note on Channel 7:

• Shares a ground with the 12V IN port but is isolated from Channels 1–6.
• Not recommended for powering sensitive effects pedals due to potential minor noise (directly sourced from the adapter). Best suited for:
• • Daisy-chaining pedals.
  • Powering noise-tolerant units (e.g., multi-effects or utility pedals).
