This AC-DC isolated step-down power supply module adopts switching power topology, directly converting 220V alternating current into stable 5V direct current. With rated output of 700mA and total power up to 3.5W, it is suitable for powering various low-current electronic loads.
The built-in isolation design separates the high-voltage AC side and low-voltage DC side, which can restrain electromagnetic interference and lower the risk of electric leakage, greatly enhancing the safety of circuit operation. The module features small board size, convenient wiring and simple installation, which can be easily integrated into control equipment, sensor power supply systems and DIY experimental circuits.
Optimized internal circuit lowers heat generation during continuous light-load operation. Each package contains 5 modules, ideal for electronic enthusiasts, laboratory testing, small household equipment modification and industrial auxiliary power transformation.
Notice: Strictly distinguish AC input terminals and DC output terminals during wiring. Do not overload the module to avoid permanent damage.
