Mean Well IRM-10-5 Switching Power Supply 10W 5V 2A - Encapsulated
Overview
IRM-10-5 is the 5V output model of this series: rated current 2A, rated power 10W, typical efficiency 77%.
IRM-10 is a 10W miniature (45.7*25.4*21.5mm) AC-DC module-type power supply, ready to be soldered onto the PCB boards of various kinds of electronic instruments or industrial automation equipments. This product allows the universal input voltage range of 85~ 305 Vac. The 94V-0 flame retardant plastic case and potted with silicone enhance the heat dissipation and meet the anti-vibration demand up to 5G; moreover, it provides the fundamental resistance to dust and moisture. With the high efficiency up to 82% and the extremely low no-load power consumption below 0.1W, IRM-10 series fulfills the worldwide regulation for the low power consumption requirement for electronics. The entire series is a Class Ⅱ design (no FG pin), incorporating the built-in EMI filtering components, enabling the compliance with BS EN/EN55032 Class B; the supreme EMC features keep the end electronic units from electromagnetic interference.

Test conditions and notes6
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
- 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
- 3. Tolerance : includes set up tolerance, line regulation and load regulation.
- 4. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
- 5. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
- 6. The power supply is considered as an independent unit ,but the final equipment still need to re-confirm that the whole system complies with the EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )

FAQ
Can I use the IRM-10-5 for a 5V embedded controller or single-board computer?
Yes, if the controller requires a constant 5V input and the total draw stays within 2A and 10W. That makes it suitable for many embedded logic boards, controller boards, and compact computing modules that run from 5V DC. Its 85-305VAC input is also useful when the same design may see different AC mains ranges.
Is this power supply suitable for a 5V microcontroller system with sensors and communication modules?
It can be, provided the full 5V load budget remains at or below 2A. For a PCB-based embedded system that combines a controller, sensors, and communications on one regulated 5V rail, the constant-voltage 5V output is the key fit criterion. If the design needs more than 10W total, a higher-capacity power supply would be the better match.
Can the IRM-10-5 power industrial logic, interface, or monitoring electronics that run on 5V?
Yes, it is appropriate for compact 5V industrial logic and monitoring sections when their power demand stays within 10W. The miniature encapsulated PCB-mount format supports internal use in space-constrained assemblies. It is less suitable for 5V equipment that has higher inrush or sustained current needs beyond 2A.
Is the IRM-10-5 meant for indoor or outdoor environments?
The listed operating temperature is -30°C to +85°C (with load derating per the derating curve), so the thermal range is broad. However, no IP rating is provided, so the specs do not confirm weather exposure or washdown suitability. Based on the available data, it should be treated as an internal enclosed power module rather than an exposed outdoor supply.
