Frequently Asked Questions
Can I use the IRM-45-48 for a compact 48V industrial control board?
Yes, it is a constant-voltage 48V supply rated for 45.12W and 0.94A, which fits compact control or interface boards that need a regulated 48V rail within that output limit. Its encapsulated PCB mounting format and 87.0 x 52.0 x 29.5 mm size also suit enclosed equipment designs.
Is the IRM-45-48 suitable for 48V telecom or networking hardware inside an equipment enclosure?
It can work for 48V telecom or networking hardware if the load stays at or below 0.94A and 45.12W. The wide 85-305VAC input is useful where the equipment may be deployed across different AC mains ranges.
Can this power supply run a low-power 48V automation node or remote I/O device?
Yes, this model is appropriate for a 48V automation node, remote I/O unit, or similar embedded control load that needs constant 48V and draws no more than 0.94A. It is better suited to lower-power 48V electronics than to higher-current actuators or larger field devices.
Is the IRM-45-48 okay for outdoor or harsh-environment use?
The listed operating temperature is -30C to +70C, so the temperature range is broad for enclosed equipment. No IP rating is listed, so it should be treated as an encapsulated internal power supply for protected indoor housings rather than exposed outdoor or washdown locations.
How does the IRM-45-48 compare with other IRM-45 series models?
Within the IRM-45 family, the non-ST models 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. The ST versions mirror those outputs as IRM-45-5ST, IRM-45-12ST, IRM-45-15ST, IRM-45-24ST, and IRM-45-48ST, while this IRM-45-48 is the PCB mounting style version.
