Frequently Asked Questions
Can I use the IRM-45-5 for a 5V embedded computer or SBC system?
Yes, it provides constant 5V output up to 8A and 40W, which suits embedded computers, controller boards, and similar 5V electronics that need more current than small adapter supplies can provide. It is intended for loads that stay within that 8A output limit.
Is the IRM-45-5 suitable for powering 5V industrial logic or microcontroller circuits?
Yes, this model fits 5V industrial logic, microcontroller, and interface circuits that need a regulated 5V rail and draw up to 8A. Its encapsulated PCB mounting style also makes it practical for built-in power sections on control boards.
Can this power supply support a 5V test fixture or automation electronics assembly?
It can, as long as the combined 5V load does not exceed 40W or 8A. That makes it appropriate for 5V test fixtures, embedded development rigs, or compact automation electronics with higher current demand than 1A to 4A class supplies.
Is the IRM-45-5 meant for outdoor use?
The operating temperature range is -30C to +70C, which is suitable for a broad range of protected equipment environments. No IP rating is listed, so it should be used inside an enclosure rather than in exposed outdoor or wet locations.
How does the IRM-45-5 compare with other IRM-45 models?
In the IRM-45 group, the outputs are IRM-45-5 at 40W, 5V, 8A; IRM-45-12 at 45.6W, 12V, 3.8A; IRM-45-15 at 45W, 15V, 3A; IRM-45-24 at 45.6W, 24V, 1.9A; and IRM-45-48 at 45.12W, 48V, 0.94A. Matching ST versions are available for each output, and this IRM-45-5 is the PCB mounting style 5V option.
