Power supply unit mean well IRM-02-5, 2 W, AC 110–230 V, peak 5 W, black, 22.2×33.7×15 mm

Mean Well IRM-02-5 is a compact encapsulated AC-to-DC power supply designed for PCB mounting. It accepts a wide input voltage range from 85 to 305 VAC (nominal 110–230 V) and provides a single 5 V DC output with a nominal output power of 2 W and peak capability up to 5 W. The unit is certified to EN/UL/IEC 62368-1 and is supplied in a black plastic package with dimensions of 22.2 × 33.7 × 15 mm, making it suitable for space-constrained electronic and embedded applications.

Advantages

The IRM-02-5 offers a small footprint and PCB-mount encapsulated design that simplifies integration into compact devices. Its wide input range and safety certification ensure compatibility with global mains supplies and compliance with modern safety standards. Low-power output with a peak capability provides flexibility for devices with occasional higher current demands while maintaining a stable 5 V rail for sensitive electronics.

How to use

Mount the IRM-02-5 directly onto the PCB following the manufacturer’s recommended footprint and soldering guidelines. Connect the AC mains to the designated input pads and route the 5 V DC output to the target circuit, ensuring correct polarity. Observe recommended creepage and clearance distances on the PCB for safe isolation between primary and secondary circuits. Verify output voltage under expected load conditions and allow adequate ventilation when operating near the unit's peak capability.

Recommendations

Use appropriate input fusing and input filtering on the primary side when integrating this power supply into end products. For reliable long-term operation, avoid continuous operation at peak power and provide sufficient PCB copper area for heat dissipation. Ensure your final design complies with applicable installation and safety standards for the target market.
