Wannien 101v0 Power Supply Schematic [exclusive] ❲2024-2026❳

Wannien 101V0

The (often identified as model E88653 ) is a versatile power supply board frequently used in monitors and moderate-power electronic devices. A schematic for this board is essential for troubleshooting common hardware failures, such as power-on issues or display signal loss. Key Technical Specifications

Safety Warning for Repairing the Wannien 101v0

• Fuse (F1) on AC variants or reverse-polarity diode on DC input.
• Input EMI filter: Common-mode choke (Lcm) and X/Y capacitors (CX, CY) to reduce conducted emissions.
• Bridge rectifier (BR1) for AC input variants, followed by bulk electrolytic capacitor (Cbulk) rated for high voltage (e.g., 400 V for universal AC).

Output Current:

Capable of delivering up to 5 Amps , suitable for low-to-moderate power applications. wannien 101v0 power supply schematic

• Symptoms: Fuse blackened, no power.
• Schematic suspects: Bridge rectifier diode shorted, Main MOSFET (Q1) shorted D-S, NTC thermistor cracked.
• Fix: Desolder the MOSFET. If it is shorted, also check the PWM controller (UC3843) and the gate resistor (typically 10-22 Ohms).
