Wannien 101V0 Power Supply Schematic: Troubleshooting and Repair Guide

The name "Wannien 101V0" (also written as "WAN NIEN 101V0" or "Wannen Delta 101V0") is likely a manufacturer board code or a UL recognition marking (the "V0" often refers to a flame‑retardant rating). This board is a compact switched‑mode power supply that steps down mains AC voltage to a lower DC output—for example, 19V for a laptop or 8.5V for a PS2.

Comprising four diodes in a bridge configuration (or a single integrated IC), it converts AC voltage into pulsating DC.

: Frequently found in LCD monitors (like the Wan Nien 101VO series), industrial DIN rail systems, and some ATX power supply platforms.
