Wannien 101V0 Power Supply — Schematic & Guide

Note: I could not verify an exact product named “Wannien 101V0”; I’ll assume you mean a small PCB/system using a 5–12 V DC input (common for hobby boards). Below is a general, safe, and practical power‑supply schematic and explanation you can adapt for a small electronics board labeled “101V0.” Treat this as a template — verify component ratings and pinouts against your actual board.

1. The LM723 Generic Schematic (90% Match)

The heart of the 101v0 is almost certainly the LM723 voltage regulator IC. Download the official Texas Instruments LM723 datasheet (free). Look for the "High Voltage, High Current Power Supply" or "Low Voltage, High Current" application circuit. Wannien 101V0 Power Supply — Schematic & Guide

• The LED Driver IC: Look for an 8-pin chip (commonly marked OB3350, OB3353, or BD9261). If pin VCC has voltage but the OUT pin is dead, the IC is faulty.
• The MOSFET: A transistor near the LED connector. If shorted, it will blow the fuse.
• LED Strips: It is very common for the actual LED strips inside the panel to fail, causing the protection circuit to shut down the power supply. Disconnect the LED connector and test the voltage at the connector (WARNING: High Voltage Spike). If the voltage jumps to max (e.g., 150V+) and holds, the board is likely good, and your LED strips are broken.

The Wannien 101V0 is a power supply unit (PSU) designed for various applications, including industrial, medical, and commercial uses.

In this write-up, we'll provide an overview of the Wannien 101V0 power supply and guide you on where to find the schematic diagram. The LED Driver IC: Look for an 8-pin

Understanding Power Supply Schematics: A Guide to Safe and Legal Acquisition

In the world of electronics repair and DIY projects, the schematic diagram is an invaluable tool. It acts as a roadmap, showing how components like resistors, capacitors, transformers, and integrated circuits interconnect to create a functioning device. For power supplies—the unsung heroes of nearly every electronic appliance—a schematic is essential for troubleshooting failures, modifying output, or even building a clone. The search query "wannien 101v0 power supply schematic free" reflects a common desire among hobbyists and technicians: access to technical documentation without cost. However, this desire must be balanced against intellectual property rights, safety concerns, and the practical realities of sourcing such information.

1. Use an isolation transformer when testing the primary (high-voltage) side.
2. Discharge the main capacitor (100µF/400V) using a 10k ohm resistor. It holds a lethal charge.
3. Check with a multimeter first – before powering on, check for shorts between VCC and GND on the PWM IC.
4. Use a series light bulb (dim bulb tester) to limit current during first power-up.

Input Stage: Includes a standard EMI filter, bridge rectifier, and a large electrolytic smoothing capacitor (often rated for 400V–450V).
