Overview

IRM-05-24 is the 24V output model of this series: rated current 0.23A, rated power 5.52W, typical efficiency 77%.

IRM-05 is a 5W 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 77% and the extremely low no-load power consumption below 0.1W, IRM-05 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-05-24 for a small 24V PLC input, relay, or control circuit?

Yes, if the circuit needs constant-voltage 24V DC and the load stays within 5.52W and 0.23A. That suits low-power 24V industrial control and automation electronics, not higher-current 24V hardware.

Is the IRM-05-24 suitable for embedded 24V electronics inside compact industrial equipment?

It is built for compact PCB integration, measuring 45.7 × 25.4 × 21.5 mm in a miniature encapsulated package. Its output is 24V at up to 0.23A, so it fits small embedded 24V sections rather than larger field loads.

Can this model be used for a low-power 24V monitoring or signaling module?

It can be used where the module requires a regulated 24V constant-voltage source and total consumption remains within 5.52W. The wide 85-305VAC input range also supports equipment intended for varied AC input conditions.

What are the main differences between the IRM-05-24 and the other IRM-05 options?

The IRM-05 series includes IRM-05-3.3 at 4.125W, 3.3V, 1.25A; IRM-05-5 at 5W, 5V, 1A; IRM-05-12 at 5.04W, 12V, 0.42A; IRM-05-15 at 4.95W, 15V, 0.33A; and IRM-05-24 at 5.52W, 24V, 0.23A. The IRM-05-24 is the 24V version in that family, with the lowest current rating of the group because it operates at the highest output voltage.

Is the IRM-05-24 rated for outdoor use or temperature extremes?

Its operating temperature range is -30°C to +85°C, with output derating per the derating curve, which supports use in equipment exposed to a wide temperature span. No IP rating is listed, so it should be treated as a protected internal power component rather than an outdoor-exposed supply.
