Wannien 101v0 Power Supply Schematic -
: The blueprint integrates a standard voltage regulation IC designed to step down erratic supply rails down to a strict, clean 5V output .
Draw connections from the IC pins using datasheets:
The most significant finding for repairing a Wannien 101V0 came from a different device—a . In that unit, a visibly burnt resistor R13 had an unknown value. By referencing the same board in a working LYONN 800VA UPS , the technician physically located R13 and read its marking: "01C" . This marking directly decodes to a 10kΩ resistor, which was then used to successfully repair the UPS .
: Check enthusiast sites like BadCaps.net or Samy's Arcade Repair . Users often upload hand-drawn diagrams or high-resolution photos of the trace side of the board. wannien 101v0 power supply schematic
Check the input section of the board for open fuses if there is no power at all.
A particularly valuable and reliable resource was a , which uses the same Wannien 101V0 board as the malfunctioning 500VA model. Because the 101V0 was unlabeled on the faulty unit, the known-good board from the 800VA UPS was used to physically locate and identify the correct component values, confirming that R13 is a 10kΩ resistor .
The serves as the technical map for a highly dependable power board widely utilized across various electronic hardware, industrial devices, and specific computer monitor displays. Often recognized alongside its UL file number or board designation, E88653 , this board is a staple for technicians dealing with power supply maintenance. : The blueprint integrates a standard voltage regulation
Act as the primary switches for individual power output rails (OUT1 - OUT4). Electrolytic Capacitors
Look for bulging or leaking capacitors , a notorious point of failure in these older boards.
: Reapply high-quality non-conductive thermal paste behind the primary switcher MOSFET and the secondary rectifiers where they clamp onto their respective aluminum heatsinks. By referencing the same board in a working
Utilizes an IC regulator to step down the input to a precise 5V DC.
(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
: High-speed Schottky barrier diodes manage the high-frequency secondary output.
