## Summary description

Mean Well IRM-03-5S is a compact 3 W power adapter/inverter designed for wide AC input applications (85–305 V). It provides a regulated 5 V DC output and complies with RoHS. With dimensions 24×37×16 mm the module is suitable for embedded electronics, IoT devices, small instrumentation and industrial control boards where low-power, wide-input voltage conversion is required.

## Long description

Mean Well IRM-03-5S is a compact encapsulated AC-DC module that converts a wide mains input into a regulated 5 V DC output. Designed for SMD mounting and low-power applications, this 3 W adapter accepts 85–305 VAC and delivers up to 0.6 A at 5 V. Its small footprint and sealed construction make it suitable for embedded electronics, IoT modules, small instrumentation and industrial control boards where stable low-voltage supply and wide input tolerance are required.
Advantages
The module provides a regulated 5 V output with up to 0.6 A load capability while supporting a wide AC input range of 85–305 VAC. Encapsulated construction improves resistance to dust and vibration and simplifies integration into compact assemblies. The SMD package and small dimensions reduce board space and facilitate automated placement. Compliance with RoHS standards ensures the design aligns with common environmental and manufacturing requirements.
Suitable for
Embedded single-board computers and microcontroller modules
IoT sensors and communication nodes
Small instrumentation and measurement devices
Industrial control boards and automation interfaces
Key specifications
Type: AC-DC single output encapsulated power module
Output voltage: 5 V DC
Maximum output current: 0.6 A
Rated power: 3 W
Input voltage range: 85–305 V AC
Mounting: SMD (surface-mount device)
Construction: encapsulated/sealed module
Typical application area: low-power embedded and industrial electronics
Dimensions: 24 × 37 × 16 mm
How to use
Mount the module on the PCB according to the manufacturer’s recommended footprint, ensuring correct polarity and secure solder joints for reliable connection. Provide AC mains input within the specified 85–305 VAC range and connect the 5 V DC output to the target circuit, observing the 0.6 A current limit. Allow for adequate copper area or thermal vias if the board design concentrates heat, and ensure the module is installed within its ambient temperature and clearance requirements for safe operation.
Usage recommendations
For reliable long-term performance, avoid continuous operation at the maximum rated current in high ambient temperatures, implement appropriate input surge protection on the AC side, and follow good PCB grounding and layout practices to minimize noise coupling into sensitive circuits.
