MEAN WELL IRM-03 5V 3W PCB Mount Power Supply 600mA

The MEAN WELL IRM-03 is a compact, 3W PCB-mount AC to DC power supply module designed for high reliability in a wide range of applications. It accepts a broad universal AC input voltage range of 85V to 305V, making it suitable for use across different regions and in environments with unstable mains power.

This efficient module features a remarkably low no-load power consumption of less than 0.075W, helping to reduce overall energy usage and heat generation. It is engineered for robust performance, incorporating built-in protections against short circuits, overloads, and overvoltage conditions to ensure the safety and longevity of both the power supply and the connected device.

The IRM-03 series complies with the EN55032 Class B EMI standard without requiring any additional external filtering components, simplifying design-in and saving valuable PCB space. It utilises free air convection for cooling, eliminating the need for a fan or heatsink, and is constructed as an isolated Class II device for enhanced safety.

With its miniature footprint and fixed 5VDC output capable of delivering up to 600mA, this power supply is an ideal choice for powering low-voltage logic circuits, microcontrollers, sensors, and other electronic subsystems within IT equipment and industrial controls.
