1. Key Challenge: “Exclusive” & Uncommon Brand

• Wannien is not a major brand like Mean Well, Delta, or TDK-Lambda. It’s likely a smaller Chinese OEM.
• “Exclusive” suggests the schematic is proprietary, not publicly released.
• Many generic power supplies use common topologies (e.g., UC3842, TL494, OB2263) but with custom PCB layouts. Without the actual unit, tracing the exact schematic is difficult.

• Input: 100–240V AC
• Output: Likely 12V, 24V, or 48V DC (check label)
• Topology: Flyback or forward converter
• Controller IC: Possibly a PWM chip like UC3842/3843 or an integrated power switch (e.g., TOPswitch)

• The power supply features a carefully designed EMI filter and shielding to minimize electromagnetic interference (EMI) and ensure reliable operation.

Failed MOSFETs: Switching transistors may fail "open" or "shorted," preventing the supply from oscillating. Inside the Wannien 101V0: An Exclusive Look at

C. Transformer

The transformer is the isolation barrier. Wannien is not a major brand like Mean
