The Wannien 101V0 Power Supply: A Complete Repair & Schematic Breakdown
: This power supply has a non-isolated primary side with hazardous voltages. Do not probe unless you are experienced with live SMPS troubleshooting.
These boards have also been found as the driving engine in generic switching power supplies intended for general electronics repair, robotics, and embedded systems. wannien 101v0 power supply schematic repack
The (often labeled under model E88653 ) is a switching power supply board primarily used in LCD monitors. A "repack" in this context typically refers to a consolidated documentation package or a kit of replacement components (like capacitors) specifically selected to address common failure points in the unit. Key Specifications & Features
A high-capacity bulk capacitor (typically rated at 450V to withstand peak AC fluctuations) smooths out the rectified output to generate a stable high-voltage DC bus line (~170VDC for 120VAC lines, or ~340VDC for 240VAC lines). 3. Pulse Width Modulation (PWM) and Switching The Wannien 101V0 Power Supply: A Complete Repair
A Pi-filter arrangement (electrolytic capacitors flanking an inductor) smooths the switching ripple into clean DC output.
Because the Wannien 101V0 is a generic board, a failure in one device can offer clues for another. For instance, a technician repairing a UPS found that the feedback circuit resistors (R13, R89, R80) were burnt. After failing to find a schematic online, they disassembled a different but similarly sized UPS from the same brand. They found the identical Wannien 101V0 board. By comparing the components, they discovered that the burnt SMD resistor, R13, had a marking of "01C", which identified it as a 10k Ohm resistor. The (often labeled under model E88653 ) is
(frequently cross-referenced under model number ) is a critical electronics component used extensively in legacy LCD monitors, industrial displays, and specialized automation hardware. Because these boards are aging, technicians frequently rely on a schematic repack —a consolidated, cleaned-up documentation package containing circuit diagrams, component listings, and voltage maps—to diagnose issues like complete power loss or screen flickering.
| Component | Value | Source/Context | | :--- | :--- | :--- | | | 01C = 10k Ohm | Discovered by comparing two UPS boards with the same failure mode | | R89 & R80 | 0.1 Ohm / 3 Watt | Used in the load sensing circuit for UPS and charger systems | | Main Fuse | T3.15A or 5A (Varies by model) | 250V Slow Blow fuse | | X2 Capacitor | 0.33µF | Used in the input EMI filtering stage | | Diodes | PK MUR 460 (Ultrafast) | Used in the primary switching circuit |
