Power adapter/inverter Mean Well IRM-03-15S, 3 W, input 85–305 V, output 15 V, RoHS, 24×37×16 mm

Mean Well IRM-03-15S is a compact 3 W AC-DC single-output encapsulated power module designed for board-level integration. It accepts a wide input range of 85–305 VAC and provides a fixed 15 V DC output at up to 0.2 A. With a small footprint of 24 × 37 × 16 mm and RoHS compliance, this module is suitable for low-power industrial, embedded and consumer electronic applications that require a reliable 15 V supply in a compact form factor.

Advantages

The IRM-03-15S combines a wide universal input range with a stable regulated output in an encapsulated SMD-compatible housing, enabling flexible installation on PCBs or within enclosures. Its small dimensions and low power rating make it suitable for space-constrained designs and low-current loads. Compliance with RoHS ensures reduced hazardous substances for environmentally conscious projects.

How to use

Install the module on the PCB according to the manufacturer’s recommended footprint and soldering guidelines. Ensure the input is connected to an AC source within the 85–305 VAC range and observe polarity on the DC output terminals. Provide adequate clearance and thermal paths on the PCB to allow heat dissipation under continuous load. Verify output voltage under expected load conditions before final system integration.

Recommendations

For reliable operation, operate the module within its specified input voltage and output current limits, allow adequate ventilation, and avoid exposure to moisture or corrosive environments. Use appropriate input fusing and transient protection where required by the application. When integrating into critical systems, perform validation tests across the full input range and temperature conditions.
