Wannien 101v0 Power Supply Schematic Repack

| Section | Components | Function | | :--- | :--- | :--- | | | L1 (Common mode choke), C1, C2 | Suppresses noise back to the mains. | | Rectification | D1-D4 (GBU806) or equivalent bridge rectifier | Converts 110-240V AC to 300-340V DC. | | Primary Switching | Q1 (MOSFET – often 10N60), U1 (PWM IC) | Converts DC to high-frequency AC (40-100 kHz). | | Transformer | T1 (EFD30 or EQ30 core) | Isolates primary from secondary. | | Secondary Rect. | D5 (24V Schottky), D6 (5V Schottky) | Converts HF AC back to DC. | | Feedback | U2 (TL431), U3 (PC817 optocoupler) | Regulates the output voltage. |

The main relay clicks, but the logic board doesn't boot. The Fix: This is unique to the 101v0. The 5V rail is derived from a separate winding on T1. Check: wannien 101v0 power supply schematic repack
