Frequently Asked Questions
Can I use the IRM-45-48ST in a 48V building automation or panel-control application?
Yes, if the automation load needs constant 48V and stays within 0.94A and 45.12W, this model is a fit. The screw terminal style makes it suited to enclosed control assemblies where a 48V output is required.
Is the IRM-45-48ST a good choice for 48V security, access, or communications electronics inside a cabinet?
It can be used for 48V security, access, or communications electronics that operate within the 45.12W and 0.94A output limit. The 85-305VAC input also helps when the same equipment platform may be used across different AC input ranges.
Can this model power a small 48V embedded or industrial interface device continuously?
Yes, it is intended for constant-voltage 48V loads and is sized for smaller embedded or industrial interface devices up to 0.94A. For equipment that needs more than 45.12W, a higher-output 48V IRM model would be the better match.
Can the IRM-45-48ST be used in unconditioned indoor spaces?
Its specified operating range is -30C to +70C, so it can handle a wide span of indoor equipment temperatures when mounted inside protected hardware. Because no IP rating is listed, it should not be treated as an exposed outdoor power supply.
What are the main differences between the IRM-45-48ST and other IRM-45 series options?
The IRM-45 series includes 5V, 12V, 15V, 24V, and 48V outputs: IRM-45-5 at 40W and 8A, IRM-45-12 at 45.6W and 3.8A, IRM-45-15 at 45W and 3A, IRM-45-24 at 45.6W and 1.9A, and IRM-45-48 at 45.12W and 0.94A. Each of those also has an ST version, and this IRM-45-48ST is the 48V, 45.12W, 0.94A screw terminal style model with 109.0 x 52.0 x 33.5 mm dimensions.
