AJMRTC HLKPM03 isolated ACDC switching stepdown power supply module is an encapsulated compact power converter for mainspowered lowvoltage electronics. It accepts universal AC input 85265V, compatible with 220V household mains, and outputs steady 3.3V DC rated 3W power. The reinforced 3000VAC isolation barrier separates highvoltage AC side and lowvoltage DC side, suppressing surge noise and enhancing user and circuit safety. Builtin selfrecovery protective functions handle shortcircuit and overcurrent events without permanent module damage. Optimized switching circuit brings high efficiency and small output ripple, supporting stable continuous operation. Throughhole pin layout allows direct soldering onto printed circuit boards. This module fits IoT controllers, smart household hardware, sensor power supply, electronic teaching experiments and various embedded secondary development projects. Basic circuit wiring knowledge is required during usage.
