Frequently Asked Questions
Can I use the IRM-90-48ST for a 48V industrial control cabinet or panel supply?
Yes, it is a constant-voltage 48V power supply rated for up to 1.88A and 90.2W, which fits many industrial control and panel-level 48V loads. The screw terminal style makes it a practical choice where a compact encapsulated supply is needed in control equipment powered from 80-305VAC.
Is the IRM-90-48ST a good fit for 48V building automation or machine-control subsystems?
It can be used for 48V automation and machine-control subsystems when the connected load requires constant 48V DC and stays within 1.88A. The wide 80-305VAC input range also makes it usable across installations with different AC input conditions.
Can this model power a 48V communications, alarm, or supervisory device inside equipment?
Yes, it can support 48V communications, alarm, or supervisory devices in enclosed equipment as long as total demand does not exceed 90.2W. This model is best matched to applications that need a fixed 48V output rather than an adjustable or constant-current source.
Would the IRM-90-48ST work for a serviceable OEM product that uses 48V DC internally?
It is suitable for OEM products that need internal 48V DC power up to 1.88A and benefit from an encapsulated construction. Compared with the PCB mounting version, this ST version uses a screw terminal style and has a larger 109.0 × 52.0 × 33.5 mm footprint at 0.219 kg.
What is the difference between the IRM-90-48ST and IRM-90-48?
Both models have the same electrical rating: 90.2W, 48V, 1.88A, constant-voltage operation, 80-305VAC input, and -30°C to +80°C operating temperature. The difference is the mechanical format: IRM-90-48 is PCB mounting style at 87.0 × 52.0 × 29.5 mm and 0.197 kg, while IRM-90-48ST is screw terminal style at 109.0 × 52.0 × 33.5 mm and 0.219 kg.
Can the IRM-90-48ST be used in outdoor or temperature-variable locations?
Its rated operating range is -30°C to +80°C, so the temperature specification covers both cold and hot equipment environments. No IP rating is provided in the listed specs, so it should be used in protected indoor housings or sheltered enclosures instead of exposed outdoor conditions.
