MEAN WELL 3W PCB Mount AC/DC Power Supply 24V 125mA

The MEAN WELL IRM-03 series is a compact and efficient 3W AC to DC power supply module, designed for direct PCB mounting. Its universal input range of 85VAC to 305VAC makes it suitable for global applications, automatically adapting to various mains voltages without the need for manual switching.

This high-reliability module is engineered with built-in protections including short circuit, overload, and overvoltage safeguards, ensuring the connected circuitry remains secure. It features excellent energy efficiency with a no-load power consumption of less than 0.075W, helping to reduce overall system standby power.

A significant advantage is its compliance with the EN55032 Class B EMC standard without requiring any additional external filtering components, simplifying design-in and reducing board space and Bill of Materials (BOM) cost. The module incorporates built-in EMI filtering and utilises free air convection for cooling, eliminating the need for a fan or heatsink in many applications.

Constructed as a fully isolated Class II device, it enhances safety by providing reinforced insulation between the input and output. Its miniature footprint makes it ideal for space-constrained applications within IT equipment (ITE) and other compact electronic devices.
