MEAN WELL IRM-03 Series 3W AC-DC Power Supply 9V 333mA

The MEAN WELL IRM-03 Series is a highly efficient, 3W miniature AC to DC power supply module, designed for compact and reliable operation. This PCB mount unit accepts a universal input voltage range from 85VAC to 305VAC, making it suitable for international applications without requiring a separate voltage selector.

Engineered for low energy consumption, it features an exceptionally low no-load power usage of less than 0.075W, helping to reduce overall system power draw. The module complies with the EN55032 Class B EMC standard without needing any additional external components, simplifying design-in and saving valuable board space. Comprehensive protection is built-in, including safeguards against short circuits, overloads, and overvoltage conditions, enhancing the durability and safety of your end product.

Cooling is achieved through efficient free air convection, eliminating the need for noisy fans or heatsinks. It is constructed as a Class II isolation device, incorporating built-in EMI filtering components to ensure clean power output and minimise electrical interference. This design prioritises high reliability for continuous operation in a variety of environments.

With a single fixed output of 9VDC at 333mA, this power supply is an ideal choice for a wide range of low-power electronic devices and systems. Its miniature footprint, combined with robust features, makes it a perfect core component for IT equipment, industrial controls, and other embedded applications where space and reliability are critical.
