Schematic: Wannien 101v0 Power Supply

If it just has bulging caps or a blown fuse: Use the TL494 reference design from the Texas Instruments datasheet as your schematic. Every pin on that IC will match your Wannien board.

Disclaimer: Power supplies contain lethal voltages in the primary capacitors (320V DC). Discharge them with a resistor before touching. Safety first. wannien 101v0 power supply schematic

Manufacturers like Wannien often buy OEM PCBs (Printed Circuit Boards) and put them in a silver perforated metal case. The "101V0" is likely a batch code or internal revision number, not a unique design. Forget searching for Wannien 101v0 schematic.pdf . Instead, open the unit and look for the PWM Controller IC .
