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-30-24 for a 24V PLC, I/O module, or industrial controller?

Yes, this model provides constant 24V output with up to 1.3A and 31.2W. That makes it suitable for small 24V PLCs, I/O modules, and compact industrial controllers that stay within those limits.

Is the IRM-30-24 suitable for 24V sensors, relays, and compact automation devices in one system?

It can be used for multiple 24V sensors, relays, and other compact automation devices if the combined load does not exceed 1.3A or 31.2W. The 85-305VAC input range is useful when equipment may be installed in different AC supply environments.

Can this model power a 24V HMI or panel control circuit in a small enclosure?

It can power a 24V HMI or panel control circuit when the load fits within the 24V, 1.3A, and 31.2W rating. Its 69.5 × 39.0 × 24.0 mm footprint supports use in compact PCB-based equipment.

Is the IRM-30-24 meant for PCB-mounted 24V embedded or industrial electronics?

Yes, this is the PCB mounting style version of the 24V IRM-30 model. It combines a constant 24V output, 1.3A current rating, and 31.2W power level in a compact 69.5 × 39 × 24 mm package.

How does the IRM-30-24 compare with the other IRM-30 output versions?

In the IRM-30 range, the comparable choices are IRM-30-5 and IRM-30-5ST at 30W, 5V, 6A; IRM-30-12 and IRM-30-12ST at 30W, 12V, 2.5A; IRM-30-15 and IRM-30-15ST at 30W, 15V, 2A; IRM-30-24 and IRM-30-24ST at 31.2W, 24V, 1.3A; and IRM-30-48 and IRM-30-48ST at 30.2W, 48V, 0.63A. This model is the PCB mounting style 24V option, while IRM-30-24ST carries the same 24V, 1.3A, and 31.2W output in screw terminal style.

Can the IRM-30-24 be used in outdoor or temperature-variable industrial equipment?

The operating temperature range is -30°C to +85°C (with load derating at higher ambient temperatures per the derating curve), so it can suit equipment that sees cold starts and elevated internal temperatures. No IP rating is listed, so it should be used in a protected enclosure instead of an exposed outdoor location.
