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 the IRM-60-24ST be used for 24V machine control or factory automation loads?

Yes, if the equipment needs a constant 24V output and the total demand stays within 2.5A and 60W. That makes it suitable for many 24V control and automation loads used inside machinery or control cabinets.

Is this a good fit for 24V industrial I/O, relays, and interface boards?

It can be, as long as the 24V I/O or interface hardware does not exceed 2.5A combined. Because it is a constant voltage model, it is intended for equipment that expects a stable 24V DC rail.

Can I use the IRM-60-24ST for 24V embedded devices or communications modules?

Yes, for 24V embedded or communications equipment that remains within the 60W output rating. The 85-305VAC input range is also helpful for equipment that may see different AC supply conditions.

Would the IRM-60-24ST work for 24V signage or control accessories inside equipment?

It is appropriate for 24V accessories when the total load is no more than 2.5A. This model is matched to 24V systems, so it should be selected only when the downstream equipment is specified for 24V DC.

Can this power supply be used in unprotected outdoor conditions?

The operating temperature range is -30°C to +85°C, with output derating at higher temperatures per the derating curve, which supports a wide range of equipment temperatures. However, no IP rating is provided, so it is better suited to protected enclosures and indoor use than to direct outdoor exposure.

What are the output differences across the IRM 60 family?

IRM-60-12 and IRM-60-12ST are 60W, 12V, 5A; IRM-60-15 and IRM-60-15ST are 60W, 15V, 4A; IRM-60-24 and IRM-60-24ST are 60W, 24V, 2.5A; IRM-60-48 and IRM-60-48ST are 60W, 48V, 1.25A. IRM-60-5 and IRM-60-5ST are 50W, 5V, 10A, so the family choice comes down to required voltage, corresponding current, and whether you want the ST screw terminal version.
