From the project
Linear power supply, with digital control
This is the second iteration of my linear power supply project available on GitHub, building upon the foundation of my original design. While the first version served as an excellent learning experience, the DW3005T aims to improve upon its predecessor with enhanced performance, better stability, and a more professional design.
- 30V 5A output - Very small output resistance - Precise voltage, current and power measurements - Small output noise - Digital controll - rotary encoder
