A20112 Power Supply Schematic ~repack~ Access

The "A20112" identifier is most commonly associated with a 12V 10A (120W) switching power supply board  often found in DIY 3D printers, CCTV systems, and universal AC-to-DC converters . The "Story" of the A20112 Power Supply

6. Conclusion

The A20112 is a robust industrial power supply, but due to the age of the electrolytic capacitors inside, most surviving units require a "recap" maintenance service to ensure reliability. If a schematic diagram is required for component-level repair, it is recommended to search for schematics of similar Delta Electronics 150W ATX power supplies from the same era, as the control circuits are often similar. a20112 power supply schematic
