Overview

IRM-60-48 is the 48V output model of this series: rated current 1.25A, rated power 60W, typical efficiency 91%. Type Blank: PCB mounting style.

IRM-60 is a 60W miniature (87*52*29.5mm) AC-DC 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 85~ 305 Vac. The 94V-0 flame retardant plastic case and potted with silicone enhance the heat dissipation. PCB mounting style model(Blank) meet the anti-vibration demand up to 2G and screw terminal style model (ST) meet the anti-vibration demand up to 5G; moreover, it provides the fundamental resistance to dust and moisture. With the high efficiency up to 91% and the extremely low no-load power consumption below 0.15W, IRM-60 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 supreme EMC features keep the end electronic units from electromagnetic interference. In addition to the PCB mounting style model, IRM-60 series also offers the screw terminal style model (ST).

Test conditions and notes5

1. All parameters NOT specially mentioned are measured at 230Vac input, rated load and 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. 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).
5. The power supply is considered as an independent unit ,but the final equipment still need to re-confirm that the whole system complies with the 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-60-48 in a 48V industrial control or automation panel?

Yes, this is a constant voltage 48V power supply rated for 60W and 1.25A. Its miniature encapsulated PCB mounting style and 87.0 x 52.0 x 29.5 mm size make it better suited to compact internal industrial or automation equipment than open-frame supplies.

Is the IRM-60-48 suitable for embedded 48V electronics inside OEM equipment?

It can fit embedded 48V designs that need up to 1.25A from a constant voltage source. The encapsulated construction, 0.195 kg weight, and PCB mounting style support use inside space-constrained OEM assemblies.

Can this 48V power supply run low-current telecom or networking hardware that uses 48V DC?

It is appropriate for 48V DC loads that stay within 60W and 1.25A. For telecom, networking, or control hardware, the key match is a regulated 48V constant voltage input within that power budget.

Would the IRM-60-48 work for a compact 48V monitoring or instrumentation system?

Yes, if the monitoring or instrumentation load requires 48V DC and does not exceed 1.25A. The wide 85-305VAC input also helps when the same design may be used across different AC mains ranges.

How does the IRM-60-48 compare with other IRM 48V models?

Within the IRM-60 series, the 48V models are this IRM-60-48 (PCB mounting style, 87 x 52 x 29.5 mm) and the IRM-60-48ST (screw terminal style, 109 x 52 x 33.5 mm), both rated 60W, 48V, 1.25A. Other IRM-60 versions offer 5V, 12V, 15V or 24V outputs.

Is the IRM-60-48 suitable for outdoor or harsh-environment use?

The provided specs list an operating temperature range of -30°C to +85°C, with output derating at higher temperatures per the derating curve, but no IP rating is provided. That means the temperature range is broad, but outdoor or washdown suitability is not established by the listed specs alone.
