Overview

IRM-90-15ST is the 15V output model of this series: typical efficiency 92.5%. Type ST: Screw terminal style.

IRM-90 is a 90W miniature (87*52*29.5mm) AC-DC PCB-mount module type power supply, ready to be soldered onto the PCB boards of various kinds of electronic instruments or industrial automation equipments. This product allows the universal input voltage range of 80~305Vac. The 94V-0 flame retardant plastic case and potted with silicone enhance the heat dissipation and meet the anti-vibration demand up to 2~5G anti-vibration by model; moreover, it provides the fundamental resistance to dust and moisture. With the high efficiency up to 93% and the extremely low no-load power consumption below 0.3W, IRM-90 series fulfills the worldwide regulation for the low power consumption requirement for electronics. The entire series is a Class Ⅱ design (no FG pin), incorporating the built-in EMI filtering components, enabling the compliance with BS EN/EN55032 Class B; the super EMC features keep the end electronic units from from electromagnetic interference. In addition to the PCB mounting style model, IRM-90 series also offers the screw terminal style model (ST).

Test conditions and notes8

1. All parameters NOT specially mentioned are measured at 230Vac input, rated load and 25℃ of ambient temperature.
2. 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
3. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
4. Tolerance : includes set up tolerance, line regulation and load regulation.
5. Derating may be needed under low input voltages. Please check the derating curve for more details.
6. Leakage current was measured from primary input to DC output.
7. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
8. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )

FAQ

Can I use the IRM-90-15ST for a 15V industrial automation controller?

Yes, if the controller needs constant voltage 15V and stays within 85.05W or 5.67A. That output level suits higher-power 15V industrial control and automation assemblies.

Is this a good power supply for 15V embedded equipment in a compact enclosure?

It can work well for embedded equipment that needs one internal 15V AC-DC module. The unit is encapsulated, measures 109.0 x 52.0 x 33.5 mm, and accepts 80-305VAC input while delivering 85.05W at 15V.

Can the IRM-90-15ST power multiple 15V control or interface loads from one source?

Yes, this model provides up to 5.67A on a 15V constant voltage output, with 85.05W total power. That makes it suitable for consolidated 15V control, interface, or monitoring loads inside industrial equipment.

Is the IRM-90-15ST appropriate for IT or industrial equipment that uses screw terminal style?

Yes, the screw terminal style is part of this model's feature set, and the supply is rated for 15V, 85.05W, and 5.67A. It is intended for internal use in equipment that needs a compact encapsulated AC-DC supply rather than a chassis power supply.

How does the IRM-90-15ST compare with the other IRM-90 outputs?

Across the IRM-90 family, the 12V models are 80.4W and 6.7A, the 15V models are 85.05W and 5.67A, the 24V models are 90W and 3.75A, and the 48V models are 90.2W and 1.88A. The ST version keeps the same 15V electrical rating as IRM-90-15 but uses screw terminal style instead of PCB mounting style.

Can this model be used in cold or high-heat indoor environments?

Its operating temperature range is -40C to +85C, with output derating at higher temperatures per the derating curve, so it covers both cold and hot indoor equipment spaces. No IP rating is provided, so the specs do not establish outdoor weather exposure suitability.
