Compact 45W AC/DC PCB mount power supply with universal input, short circuit/overload protection, and LPS compliance from MEAN WELL.
The MEAN WELL AC/DC PCB Mount Power Supply from the IRM-45 series is a compact, high-efficiency module designed to deliver reliable performance in a wide range of electronic applications. Featuring a universal input voltage range of 85–264VAC, this power supply ensures compatibility with mains supplies worldwide, making it an excellent choice for global IT equipment and industrial systems.
Despite its miniature size, this unit offers a robust output of up to 45W, with a fixed single output available in various voltages to suit diverse load requirements. The module is engineered with comprehensive protection features, including short circuit, overload, and over voltage safeguards, ensuring both the power supply and the connected equipment remain safe under abnormal conditions.
Cooling is achieved through free air convection, which eliminates the need for additional fans and contributes to a quieter, more reliable operation. The power supply also complies with LPS (Limited Power Source) standards and features an exceptionally low no-load power consumption of less than 0.1W, minimising energy waste when the system is in standby mode.
With a PCB-mount design and a highly compact footprint, this power supply is ideal for integration into space-constrained enclosures, such as those found in telecommunications, networking, and specialised industrial equipment. RoHS compliance and the absence of SVHC substances (as of June 2025) underline its commitment to environmental safety and sustainability.
Whether you are designing a new system or replacing an existing power module, the MEAN WELL IRM-45 series offers a trusted, efficient, and protected power solution that meets stringent international standards.
