5V 2.4A AC-DC Power Supply Module – Isolated SMPS for Industrial & IoT Applications

Deliver safe, reliable, and efficient power to your critical electronics with this compact, fully-isolated 12W AC-DC switching power module. Designed for seamless integration into industrial equipment, IoT devices, and embedded systems, it converts a wide-ranging 90–305V AC input into a stable, regulated 5V DC output capable of delivering up to 2.4A (12W).

Its high-efficiency switching design ensures minimal power loss and low heat generation, while ultra-low standby consumption makes it ideal for energy-sensitive or always-connected applications. The module features robust galvanic isolation, protecting sensitive downstream circuits from dangerous AC line voltages and electrical noise. Built-in safety mechanisms—including over-voltage, over-current, and short-circuit protection, plus a resettable fuse—ensure automatic fault recovery and prevent damage to both the power supply and your connected devices.

Housed in a compact, shielded metal case (38x28x20mm) with through-hole mounting pins, this module offers a durable, space-saving, and EMI-compliant power solution that is ready for direct PCB integration in the most demanding environments.
