Overview

IRM-02-15S is the 15V output model of this series: rated current 133mA, rated power 2W, typical efficiency 75%. Type S: SMD style.

IRM-02 is a 2W miniature (33.7*22.2*15mm) 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 a universal input voltage range of 85~305Vac. The phenolic case and potted with silicone enhance the heat dissipation and meet the anti-vibration demand up to 5G; moreover, it provides the fundamental resistance to dust and moisture.

FAQ

Can I use the IRM-02-15S in a compact 15V embedded or automation board?

Yes, if the board requires a 15V constant-voltage supply and total draw stays within 2W and 133mA. The SMD style and 33.7 × 22.2 × 16.0 mm package make it suitable for dense internal designs.

Is the IRM-02-15S suitable for low-power 15V industrial monitoring electronics?

It can work for small monitoring or interface electronics that need 15V and stay below 133mA. Loads above the 2W rating need a higher-power 15V supply, as 2W is the rating of this series.

Can this power supply be used where the AC input may vary across regions?

Yes, the input is rated 85-305VAC, so it supports a wide AC range. On the DC side, it remains a 15V constant-voltage supply with a 2W maximum output.

Does the IRM-02-15S support outdoor or washdown use?

Its operating temperature range is -30°C to +85°C, subject to the derating curve, which is broad for enclosed equipment. Since no IP rating is listed in the supplied specs, it should be treated as an indoor protected component rather than an outdoor-rated unit.

What are the main differences between IRM-02-15S and other 15V IRM options?

This datasheet covers only the 2W IRM-02 series, so it does not specify other 15V IRM power levels. At the 2W level, IRM-02-15 is the PCB mounting style version (33.7 × 22.2 × 15 mm) and IRM-02-15S is the SMD style version (33.7 × 22.2 × 16 mm), both rated 15V and 133mA.
