Wannien 101v0 Power Supply Schematic Verified ~upd~ May 2026
In the dimly lit workshop of "The Circuit Breakers," a small team of engineers stood huddled around a single, glowing monitor. They had been working for weeks on a critical project: a high-performance power supply unit for a new industrial automation system. The stakes were high—the system’s reliability depended entirely on the stability of this power source.
- Signal Path: TL494 Output → TIP122 (Base) → Main Transformer Primary.
- On the secondary side: Rectified DC → 2N3055 pass transistor → Output.
- Transformer secondary → fast diode → output capacitor → output terminals.
- Feedback: output (+) → resistor divider → TL431 ref → TL431 cathode → optocoupler LED.
