HLK PM03 Hi-Link 3.3V 3W AC to DC Power Supply Module The HLK-PM03 from Hi-Link is a compact AC-to-DC switching power supply module that converts standard mains AC voltage into a regulated 3.3 V DC output with up to 3 W of power. It integrates the switching regulator, isolation transformer, and protection circuitry into a single, PCB-mountable module. This makes it an easy, space-efficient choice for powering low-voltage digital electronics and microcontroller systems directly from AC mains without needing a bulky external adapter.Click here to view related productsFeaturesWide AC input range — works with typical mains voltagesRegulated 3.3 V DC output — ideal for modern low-voltage digital circuitsUp to 3 W output power — suitable for small embedded systemsCompact PCB mount module — saves space in designsHigh efficiency — low heat and energy lossLow ripple and noise — clean enough for many digital and analog circuitsBuilt-in protections — safeguards against overload and short conditionsIsolation between AC input and DC output — measures safety into low-voltage sideEasy to use — simple input/output pins for fast integrationApplicationsEmbedded and IoT systems powered directly from AC mains3.3 V microcontroller and digital logic power supplyLow-power sensor and communication modulesSmart home control unitsConsumer electronics requiring 3.3 V DCPCB designs with limited space for external adaptersIndustrial control logic power feed*Product image for illustration purposes only, actual product may vary.
