Wannien 101v0 Power Supply Schematic Verified [new] -

Understanding the Wannien 101V0 Power Supply Schematic The Wannien 101V0 is a common power supply board often found in LED monitors and small electronic devices. Finding a verified schematic is essential for technicians and hobbyists looking to repair or repurpose these units rather than replacing them.

The board is typically part of a multi-board system containing the power supply, inverter (for CCFL backlighting), and mainboard. Input Range: Standard 100Vac to 240Vac. Typical Outputs: Usually provides rails to the logic board. Fuse Rating: Often uses a T3.15A 250V input fuse. Key Components to Verify

Protection and filtering on outputs

The search began. They combed through manufacturer databases, forum archives, and technical libraries. Finally, they found it: a document titled Wannien 101v0 Power Supply Schematic |verified|.

Failure #3: Blown MOSFET (Q1) without visible cause

Do not just replace Q1. On the Wannien 101v0, the verified schematic shows a gate resistor R11 (22R) and a 18V zener D6 (1N4746A) from gate to source. If D6 leaks, it keeps the MOSFET in linear region. Fix: Always replace D6 (18V Zener) and R11 simultaneously with Q1. wannien 101v0 power supply schematic verified

Always discharge the large primary filter capacitor (usually 400V/450V) before handling the board to avoid high-voltage shock. Visual Inspection:

Input/Rectification: Diodes (like the 1N4001 series) and a bridge rectifier to convert AC to DC. Input Range: Standard 100Vac to 240Vac
