Isolated Guitar Pedal Power Supply Schematic

Guitar pedal power supply feature.

Isolated guitar pedal power supply schematic. Buy guitar pedal power supply 10 isolated dc output for 9v 12v 18v 100ma 300ma 500ma effect pedal with usb port for charging mobile phone tablet short circuit and over current protection cp 04. When pedals share the same power output unwanted noise and interference can be introduced to the signal. In my opinion this is a fantastic power supply that can power a wide range of pedals and each output is completely isolated. The outputs are fully isolated and extremely quiet and accommodate a variety of voltage and current requirements two 9v outputs at 100ma two 9v outputs at 300ma two 9v outputs at 450ma two 18v outputs at 250ma and in one particularly cool feature two 6 15v variable voltage.

An isolated power supply i recommend is the voodoo lab pedal power 2 plus click to see on amazon it is seen by many guitarists as the best power supply for guitar pedals available right now. Some pedal power problems can be fixed by switching to an isolated power supply. For cable connectors between the power supply and pedals i decided to use 3 5mm stereo jacks inspired by dunlop dc brick which uses mono 3 5mm jacks. When lit this led indicates a good connection.

Guitar pedal power supply 10 isolated dc output for 9v 12v 18v 100ma 300ma 500ma effect pedal with usb port for charging mobile phone tablet short circuit and over current protection cp 04 4 5 out of 5 stars 213. For example if you don t have any 5v pedals you can just swap the 5v power regulator for a 9v regulator and now you ll have double the 9v power. The iso brick boasts 10 outputs making it possible to run a wide range of pedals with noise free dc power. For the circuit board i used a thick fiberglass eyelet board and the enclosure is a custom aluminum 14 5x11x5cm box.

This phenomenon is most common in daisy chained pedals. If short circuited or overloaded this led will turn off. The schematic uses a simple power supply circuit converting ac to pulsating dc smoothing it with capacitors and running it through voltage regulators for fixed dc outputs.
