Wx-dc12003 Schematic [verified] May 2026

: A high-frequency transformer provides the 3kV galvanic isolation between the primary (hot) and secondary (safe) sides.

: Built-in overvoltage, overcurrent, overheating, and short-circuit protection. Schematic and Circuit Architecture

: Powering sensors and wireless modules directly from wall power. wx-dc12003 schematic

: Providing power for LED drivers or small relay boards. Troubleshooting and Safety Tips 85~265V AC to 5V 3.5W DC Isolated Power Supply Module

: Approximately 80% with a no-load power consumption of less than 0.05W. : A high-frequency transformer provides the 3kV galvanic

While a single "official" datasheet is rare for these modules, reverse-engineered schematics reveal a standard .

Because of its tiny footprint (approximately 23.5 x 18.1 mm), the WX-DC12003 is a favorite for: : Providing power for LED drivers or small relay boards

: The AC input typically passes through a small EMI filter and a bridge rectifier. A high-voltage electrolytic capacitor (often 4.7µF, 400V) smooths the rectified DC.
