Frequently Asked Questions
Can I use the IRM-03-24 for a small 24V industrial sensor or control circuit?
Yes, it is a constant-voltage 24V power supply rated at 3W. That fits low-power 24V control, sensing, and interface electronics that stay within the 3W output limit.
Is the IRM-03-24 suitable for embedded 24V monitoring or signaling boards?
It can be used when the embedded load requires regulated 24V and remains within the 3W rating. The encapsulated miniature body measures 37.0 × 24.0 × 15.0 mm, which supports compact internal designs.
Would the IRM-03-24 work for low-power automation electronics that operate on 24V DC?
Yes, for smaller 24V automation modules, it provides constant-voltage output from an 85-305VAC input. It is intended for lighter 24V electronic loads rather than higher-power field devices.
Can this model be used in equipment shipped to different AC mains regions?
Yes, the specified input range is 85-305VAC, which supports broad AC input coverage. That is useful for OEM equipment using a fixed 24V, 3W internal supply across multiple markets.
Is the IRM-03-24 suitable for outdoor enclosures?
The unit is rated for operation from -30°C to +85°C, so its temperature range is broad. No IP rating is provided in the listed specs, so exposed outdoor suitability is not established by this product data.
How does the IRM-03-24 compare with other 24V IRM models?
Among 24V versions, IRM-01-24 and IRM-01-24S are 1W, 24V, 0.04A; IRM-02-24 and IRM-02-24S are 2W, 24V, 0.08A; IRM-03-24 and IRM-03-24S are 3W, 24V, 125A; IRM-05-24 is 5.52W, 24V, 0.23A; IRM-10-24 is 10.08W, 24V, 0.42A; IRM-15-24 is 15.12W, 24V, 0.63A; IRM-20-24 is 21.6W, 24V, 0.9A; IRM-30-24 and IRM-30-24ST are 31.2W, 24V, 1.3A; IRM-45-24 and IRM-45-24ST are 45.6W, 24V, 1.9A; IRM-60-24 and IRM-60-24ST are 60W, 24V, 2.5A; and IRM-90-24 and IRM-90-24ST are 90W, 24V, 3.75A. The IRM-03-24 is the PCB mounting style 3W option in that 24V family.
