This is an simple project for a 4-lines power supply bank capable of powering small household devices. This project fits exactly into a KH-6 package.
- 12-15V AC/DC power plug for external input power supply (center-negative)
- Input with polarity test (with a led indicating polarity reversal)
- Chain power-plug for a second device
- 4 isolated and stabilized 9V-100mA center-negative output (common ground)
Schematics and PCB layouts are designed with ExpressPCB free CAD software.
My usage of this project is to power audio effect pedals.
