Wannien 101v0 Power — Supply Schematic Verified

Works with the optocoupler to monitor output precision. 3. Verified Troubleshooting Steps

Often an 8-pin IC (like the LD75xx series). If this fails, the board will appear completely dead. wannien 101v0 power supply schematic verified

The primary bulk capacitor can hold a lethal charge of over 300V DC even after the unit is unplugged. Always discharge the main capacitor using a high-wattage resistor before touching the underside of the PCB. Works with the optocoupler to monitor output precision
