If you’ve landed here, you are likely staring at a dead power supply. Maybe it’s from a LED sign, a CCTV camera bank, or a 3D printer. The bad news? Official schematics for the "Wannien" brand are almost impossible to find. The good news? The 101V0 is almost certainly a clone of a very common topology. wannien 101v0 power supply schematic

Disclaimer: Power supplies contain lethal voltages in the primary capacitors (320V DC). Discharge them with a resistor before touching. Safety first. Posted by: The Bench Wizard Reading time: 4

Let’s crack this open (figuratively and literally). Based on user reports and common grey-label manufacturing, the 101V0 is typically a 12V or 24V DC switching power supply , usually rated between 100W and 150W. It is a close relative of the famous Mean Well S-100-12 or S-150-12 series. Official schematics for the "Wannien" brand are almost

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.
