Overview

IRM-30-48 is the 48V output model of this series: rated current 0.63A, rated power 30.2W, typical efficiency 90%. Type Blank: PCB mounting style.

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-30-48 for a 48V industrial control circuit or relay board?

Yes, it is a constant voltage 48V supply rated for 30.2W and 0.63A, which fits low-current 48V control and interface loads. The wide 85-305VAC input also suits equipment that may be deployed across different AC supply ranges.

Is the IRM-30-48 suitable for embedded 48V electronics inside compact equipment?

It can be a fit for compact embedded designs because its package measures only 69.5 × 39 × 24 mm. Its PCB mounting style also aligns with internal board-level power designs that need 48V constant voltage output up to 0.63A.

Can this 48V power supply run low-power automation or sensing equipment?

It is appropriate for 48V automation or sensing loads that stay within 30.2W and 0.63A. For higher-current 48V devices, this model would be undersized and a higher-output power supply would be the better match.

Is the IRM-30-48 appropriate for outdoor or harsh-environment use?

The provided specs list an operating temperature range of -30°C to +85°C (with load derating at higher ambient temperatures per the derating curve), but they do not list an IP rating. That makes it better suited to protected indoor equipment or enclosed assemblies rather than exposed outdoor use by itself.

How does the IRM-30-48 compare with other 48V models in the IRM series?

This IRM-30 spec sheet covers one other 48V version: the IRM-30-48ST, which has the same 48V, 0.63A, 30.2W output but is the screw terminal style model measuring 91 × 39.5 × 28.5 mm. The IRM-30-48 is the PCB mounting style option at 69.5 × 39 × 24 mm.
