Wannien 101v0 Power Supply Schematic | Repack

Remember: Safety first. The 340V DC bus on the primary capacitor can hold a lethal charge for hours. Always discharge C4 with a 10kΩ 5W resistor before probing.

Disclaimer: Mains voltage is dangerous. This article is for informational purposes. Consult a professional if you are not trained in high-voltage electronics. wannien 101v0 power supply schematic repack

By understanding the topology rather than relying purely on a PDF, you turn a dead PSU into a working one—and contribute to the global "repack" community. Remember: Safety first

A: Your feedback circuit is broken. Check the TL431 and the PC817 optocoupler. Without feedback, a flyback converter runs at maximum duty cycle. Refer to the "Feedback Divider" section in Part 3. wannien 101v0 power supply schematic repack
