Wannien 101v0 Power Supply Schematic ✓

: Features a standard T3.15A fuse , NTC thermistors for inrush current protection, and varistors to guard against voltage spikes.

: Utilizes a PWM controller IC (like the LD7550 or similar) to drive a power MOSFET, which chops the DC into high-frequency pulses for the transformer. wannien 101v0 power supply schematic

: Usually supports a universal range of 90Vac to 264Vac at 50/60Hz. : Features a standard T3

: High-frequency AC from the transformer is rectified by fast-recovery Schottky diodes and filtered by electrolytic capacitors to provide the final DC rails. Common Troubleshooting & Repair : High-frequency AC from the transformer is rectified
