Wannien 101v0 Power Supply Schematic Jun 2026

(frequently rated around 450V) smooths the pulsating DC before it enters the high-frequency switching stage. Switching & Transformer: PWM controller chip Power MOSFET drive the primary side of a high-frequency transformer

The output stage consists of a voltage follower circuit that provides a stable and low-noise output voltage. The output voltage is sensed by a voltage divider (R3 and R4) and fed back to the voltage regulation circuit. wannien 101v0 power supply schematic

: The "94V-0" marking on the board is a UL flammability rating , indicating the circuit board material's fire resistance, rather than a specific model number. (frequently rated around 450V) smooths the pulsating DC

Input and protection

When in doubt, trace the copper. The schematic is written on the PCB itself—follow the path from AC to DC. wannien 101v0 power supply schematic
