MEAN WELL IRM-15-05 – 15 W Isolated AC-DC Power Supply Module (5 V DC Output)

The MEAN WELL IRM-15-05 is a compact 15 W AC-DC switching power supply designed to provide a regulated 5 V output with high efficiency and safety certifications for industrial and consumer applications. Part of the popular IRM series, this module integrates all necessary power conversion and protection features in a fully encapsulated case, making it ideal for embedded and PCB-mounted designs.

Operating from a universal AC input of 85 – 264 VAC (or 120 – 370 VDC), the IRM-15-05 ensures global compatibility without additional switching requirements. It features reinforced isolation (3 kVAC) and Class II double insulation, eliminating the need for earth ground connection in most applications. The module achieves efficiency up to 84 % with minimal no-load power consumption (< 0.1 W), supporting green and energy-efficient designs.

The encapsulated construction with UL94 V-0 rated plastic housing provides superior protection against moisture, dust, and vibration. Built-in protections include short-circuit, overload, and over-voltage safeguards for long-term reliability.

Fully compliant with IEC/EN/UL 62368-1 and EMC EN55032 Class B, the IRM-15-05 is suitable for industrial automation, building control, smart IoT devices, and test equipment applications. Its small form factor (52.4 × 27.2 × 24 mm) allows it to fit easily on crowded PCBs while maintaining safe creepage and clearance distances.
