## Summary description

MEAN WELL IRM-02-12S is a compact 2 W power adapter/inverter with wide input range 85–305 V and fixed 12 V output. Designed for low-power electronic devices and embedded systems, it meets RoHS sustainability standards. Small form factor (33.7 mm depth, 15 mm height) and 19 g weight make it suited for space‑constrained installations and high‑volume integration.

## Long description

MEAN WELL IRM-02-12S is a compact encapsulated AC‑DC power module that delivers a fixed 12 V DC output at up to 0.167 A from a wide input range of 85–305 V AC. With a rated output power of 2 W and an SMD-friendly package measuring 33.7 mm deep and 15 mm high, this low-profile adapter is designed for small electronic devices, embedded systems and applications where space and weight are limited. The unit is RoHS compliant and intended for reliable low-power conversion in high-volume or tightly packed assemblies.
Advantages
The module combines a wide AC input range with a regulated 12 V output, providing stable low-current power across varied mains voltages. Its encapsulated construction offers basic protection against dust and mechanical stress while supporting surface-mount assembly methods. The small footprint and 19 g weight make installation into compact enclosures straightforward, and the single-output design simplifies integration into systems that require a dedicated low-power rail.
Suitable for
Embedded control boards and microcontroller projects
Low-power sensors and measurement electronics
Industrial indicators, relays and auxiliary circuits
Space-constrained consumer electronics and IoT devices

How to use
Place and solder the module according to the host PCB land pattern and soldering guidelines for SMD components. Ensure correct orientation and secure mains connections through the recommended solder pads or terminals. Verify input and output voltages with a multimeter before connecting sensitive loads. Allow adequate spacing around the module for heat dissipation and follow the system safety and grounding practices applicable to mains-connected equipment.
Usage recommendations
Use the adapter for low-current, continuously powered circuits and avoid connecting loads that exceed the 0.167 A rating. For applications requiring higher reliability or environmental sealing, consider additional conformal coating or enclosure protection. Observe mains safety regulations during installation and provide appropriate isolation and fusing on the primary side.
