Overview

IRM-30-5 is the 5V output model of this series: rated current 6A, rated power 30W, typical efficiency 83%.

IRM-30 is a 30W miniature (69.5*39*24mm) 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 85~305Vac. The 94V-0 flame retardant plastic case and potted with silicone enhance the heat dissipation. PCB mounting style model(Blank) meet the anti-vibration demand up to 2G and screw terminal style model (ST) meet the anti-vibration demand up to 5G; moreover, it provides the fundamental resistance to dust and moisture. With the high efficiency up to 90% and the extremely low no-load power consumption below 0.1W, IRM-30 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 superlative EMC features keep the end electronic units from electromagnetic interference. In addition to module-type model, IRM-30 series also offers the screw terminal style model (ST).

Test conditions and notes5

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. 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).
5. 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-30-5 for a 5V single-board computer or embedded controller?

Yes, it is a constant voltage 5V supply rated for 30W and up to 6A, which suits higher-current embedded controllers and processor boards. The 85-305VAC input also helps when the same design may be used across different AC input ranges.

Is the IRM-30-5 suitable for powering 5V industrial logic or USB-powered electronics inside equipment?

It can be used for 5V electronics that need a stable constant voltage source and stay within 6A and 30W. That makes it practical for internal logic, communications, and control electronics rather than for loads that require a higher output voltage.

Can this model support 5V automation accessories or HMI support electronics?

Yes, if the 5V load does not exceed 6A. The compact PCB-mount package at 69.5 × 39 × 24 mm is also useful where space is limited inside industrial or embedded assemblies.

How do I know if 30W is enough for my 5V load?

This model is sized for 5V constant voltage loads up to 6A and a total of 30W. If the connected equipment needs more than 6A or more than 30W, you would need a higher-output 5V model.

Is the IRM-30-5 meant for outdoor equipment or only protected indoor use?

The operating temperature range is -30°C to +85°C (with load derating at higher ambient temperatures per the derating curve; the 5V model derates more at 100Vac input), so it can handle a wide temperature span inside equipment. Since no IP rating is listed in the provided specs, it is better treated as a protected indoor or enclosed-system power supply rather than an exposed outdoor unit.
