Wannien 101v0 Power: Supply Schematic Verified

The Ultimate Guide to the Wannien 101V0 Power Supply Schematic

AC INPUT: Live → Fuse (5A/250V) → Switch → Transformer Primary AC INPUT: Neutral → NTC Thermistor (5D-11) → Transformer Primary

The Wannien 101V0 uses an to manage the two operating modes: Constant Voltage (CV) and Constant Current (CC).

High Equivalent Series Resistance (ESR) or physical bulging due to heat. High-value resistors (100kΩ+) Board works if warmed up, but won't start from a cold plug. wannien 101v0 power supply schematic verified

If your Wannien 101V0 board is malfunctioning, look for these common faults using the verified schematic layout: Suspect Component Diagnostic Action Bridge Rectifier or Primary MOSFET

Each of the four channels contains an independent transistor acting as an electronic gate.

pin of (PWM Controller). It should sit steadily between 12V and 18V DC. The Ultimate Guide to the Wannien 101V0 Power

: A defining layout feature of the verified Wannien 101v0 circuit diagram is its four independent transistor switch channels (designated as OUT1 through OUT4 ).

The Wannien 101V0 is a traditional Switched-Mode Power Supply (SMPS) utilizing a flyback topology. It is designed to convert high-voltage Alternating Current (AC) from a wall outlet into stable, low-voltage Direct Current (DC) required by sensitive digital logic boards.

Measure between pin 4 (GND) and pin 7 (Vcc) of the LM324. You should see between 10V and 15V DC. If this voltage is missing or oscillating, nothing else will work. If your Wannien 101V0 board is malfunctioning, look

Once filtered, the AC voltage must be converted to raw DC voltage.

Connected across the primary winding of the transformer is an RCD snubber (resistor, capacitor, and fast diode). This clamps the massive inductive voltage spikes generated when the MOSFET abruptly turns off, protecting the transistor from avalanche breakdown. 3. Transformer and Secondary Rectification

Safety Warning: Power supplies contain lethal voltages trapped in large capacitors even after being unplugged. Always discharge the bulk capacitor (C1) using a high-wattage resistor (e.g., 1kΩ / 5W) before touching any component.
