Wannien 101v0 Power Supply Schematic Verified May 2026

Corrected Component Values

Three discrepancies were identified between the initial draft and the verified board: wannien 101v0 power supply schematic verified

Always disconnect the power cord before inspecting the board. Discharge high-voltage capacitors to avoid serious shock. Visual Inspection: Check for burnt components or corroded connectors. Voltage Testing: multimeter , measure the output rails (typically 5V and 12V or 24V). Component Replacement: If the schematic identifies specific PWM controllers or MOSFETs The Wannien 101V0 (often listed as model Go

This guide assumes you have basic electronics knowledge (reading schematics, using a multimeter, soldering). The Wannien 101V0 is a common switching mode power supply (SMPS) found in many LED drivers, small appliance chargers, and industrial control units. Visual & Continuity: High-resolution images of both sides

1. Visual & Continuity: High-resolution images of both sides of the PCB were taken. A multimeter in continuity mode traced every copper trace against the drafted schematic.
2. Component Verification: Each resistor, capacitor, diode, and inductor was measured out-of-circuit (or with careful in-circuit techniques) and compared to the schematic’s bill of materials.
3. Electrical Validation: The supply was powered at 110V AC and 230V AC (50/60 Hz). Oscilloscope probes captured the switching waveform at the primary-side MOSFET gate, the auxiliary winding voltage, and the DC output ripple. Load was varied from 0% to 100% of rated current.
