Summary of Miniatur Power Supply Unit with 0..24V and 0..3A
This project is a very small switch-mode DC power supply roughly the size of a cigarette box, powered from an external 24V AC/DC SMPS. It provides an adjustable output from 0–24V and 0–3A, using a switch-mode preregulator to minimize dissipation and enable compactness. Voltage and current are shown on an RGB OLED display.
Parts used in the Miniatur Power Supply Unit with 0..24V and 0..3A:
- External 24V switch-mode AC/DC power supply (input)
- Switch-mode preregulator (DC-DC converter)
- Output adjustment/control circuitry (voltage and current regulation)
- RGB OLED display
- Output connectors (for 0..24V, up to 3A)
- Enclosure sized about a cigarette box
- Supporting passive components (resistors, capacitors, inductors)
- PCB and wiring
Very small power supply unit in the size of a cigarette box. The input voltage is 24V. Its supplied by a external switch mode AC/DC PSU.
The output voltage range is 0V to 24V at 0A to 3A. A switch mode preregulator reduces the power loss. This allows a very compact design. Voltage and current are displayed on a RGB OLED display.
