Overview

IRM-01-24S is the 24V output model of this series: rated current 42mA, rated power 1W, typical efficiency 77%.

IRM-01 is a 1W miniature (33.7*22.2*15mm) 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 a universal input voltage range of 85~305VAC. The phenolic case and the fully-potted 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 0.075W, IRM-01 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 EN55032 Class B; the supreme EMC features keep the end electronic units from electromagnetic interference. In addition to module-type model, IRM-01 series also offers the SMD style model.

FAQ

Can I use the IRM-01-24S for a small 24V industrial sensor or interface circuit?

Yes, this model is intended for low-power 24V DC loads where 1W is sufficient. It is a constant voltage supply with a 24V output and a wide 85-305VAC input range, which fits compact industrial control or interface electronics rather than higher-draw loads.

Is the IRM-01-24S suitable for embedded 24V control electronics on a compact board?

It can fit compact embedded designs because the package is 33.7 × 22.2 × 16.0 mm and the unit is described as a miniature encapsulated type with SMD style. The 24V constant voltage output and 1W power level make it appropriate for very small onboard power sections, not larger 24V subsystems.

Can this 24V power supply be used for light automation signaling circuits?

Yes, if the automation circuit needs a regulated 24V DC source and stays within the 1W rating. This model is better suited to low-consumption signaling, sensing, or control electronics than to devices that need more output power.

Is the IRM-01-24S okay for outdoor or harsh-temperature use?

The operating temperature range is -30°C to +85°C, so it covers a wide temperature span. No IP rating is listed, so it should be treated as a protected internal power module rather than a supply for exposed outdoor or wet locations.

How does the IRM-01-24S compare with other Mean Well IRM encapsulated models?

Within the 1W IRM-01 group, related options are IRM-01-3.3 and IRM-01-3.3S at 3.3V 300A, IRM-01-5 and IRM-01-5S at 5V 200A, IRM-01-9 and IRM-01-9S at 9V 111A, IRM-01-12 and IRM-01-12S at 12V 0.08A, IRM-01-15 and IRM-01-15S at 15V 0.07A, and IRM-01-24 and IRM-01-24S at 24V 0.04A. Higher-power IRM siblings then step up through IRM-02, IRM-03, IRM-05, IRM-10, IRM-15, IRM-20, IRM-30, IRM-45, IRM-60, and IRM-90 variants, covering outputs from 3.3V to 48V and power levels from 2W to 90.2W.
