Frequently Asked Questions

Can I use the IRM-45-12ST for a 12V industrial control box with sensors and small relays?

Yes, it is a constant voltage 12V supply rated for 45.6W and 3.8A, which fits 12V control loads that stay within that output. The wide 85-305VAC input also suits equipment used across different AC supply ranges.

Is the IRM-45-12ST suitable for 12V embedded controllers or HMI support circuits?

It can be a fit when the controller or support electronics require a regulated 12V output and the total load does not exceed 3.8A or 45.6W. Its encapsulated format and screw terminal style make it more aligned with enclosed equipment than open-frame power sections.

Can this 12V power supply run 12V automation accessories inside a machine cabinet?

Yes, for 12V accessories that use constant voltage and stay within 45.6W total output, this model matches that electrical requirement. Its operating temperature range is -30°C to +70°C, which supports use in a wide range of enclosed industrial environments.

What is the difference between the IRM-45-12ST and other IRM-45 models?

Within the IRM-45 range, the outputs are 5V at 8A and 40W, 12V at 3.8A and 45.6W, 15V at 3A and 45W, 24V at 1.9A and 45.6W, and 48V at 0.94A and 45.12W. The ST versions use screw terminal style, while the non-ST versions in the same output class use PCB mounting style.

Is the IRM-45-12ST suitable for outdoor or cold-temperature use?

The operating temperature range is -30°C to +70°C, so its temperature spec covers both cold and hot conditions within that band. The provided specs do not list an IP rating, so outdoor or wet-location suitability cannot be confirmed from these specs alone.
