(critical):

According to documentation from the All About Circuits forum and product listings: : 85V – 265V AC (or 100V – 370V DC). Output Voltage : 5V DC (±0.2V). Output Current : 700mA (nominal), 3.5W total power. wxdc12003 schematic better

WX-DC12003 is a compact 3.5W isolated switching power supply module (5V/700mA) that can be improved by adding a 0.25A input fuse and upgrading output capacitors to reduce noise, as noted in community discussions on Thingiverse All About Circuits (critical): According to documentation from the All About

Features a wide input range (AC 50V–277V or DC 70V–390V). It includes a full-bridge rectifier and filtering via a high-voltage electrolytic capacitor (typically 4.7µF/400V). Switching Control: WX-DC12003 is a compact 3

topology. This design eliminates the need for an optocoupler and a shunt regulator on the secondary side, which reduces component count and cost. Input Rectification

The is a popular, low-cost AC-DC switching power supply module known for its compact 3.5W output (5V at 700mA). While official manufacturer documentation is scarce, the community has reverse-engineered and improved upon its design for better reliability in DIY projects. Key Schematic & Design Details

: 5V ±0.15V at a maximum current of 700mA (approx. 3.5W). Efficiency : Approximately 80%.
