Mean Well IRM-02-24 Switching Power Supply 2W 24V 83mA - Encapsulated
Overview
IRM-02-24 is the 24V output model of this series: rated current 83mA, rated power 2W, typical efficiency 77%. Type Blank: PCB mounting 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. With the high efficiency up to 77% and the extremely low no-load power consumption below 0.075W, IRM-02 series fulfills the worldwide regulation for the low power consumption requirement for electronics.

FAQ
Can I use the IRM-02-24 to power a small 24V industrial sensor or transmitter from AC mains?
Yes, this model is a 24V constant-voltage power supply rated at 2W with 83mA output. That makes it suitable for small 24V industrial electronics that stay within those output limits and need wide 85-305VAC input support.
Is this power supply a fit for low-power 24V building automation or control PCB circuits?
It can be a fit for compact 24V control circuitry where the total load stays within 2W and 83mA. Its miniature encapsulated construction and PCB mounting style make it better aligned with embedded or board-level automation products than higher-power 24V loads.
Can the IRM-02-24 be used in a compact embedded device that needs 24V DC internally?
Yes, for embedded equipment that requires a regulated 24V constant-voltage output and does not exceed 2W. The compact 33.7 × 22.2 × 15.0 mm size and 0.024 kg weight support use in space-constrained internal assemblies.
Would this work for a small 24V relay, indicator, or interface circuit inside industrial equipment?
It is intended for low-power 24V DC loads, so it can suit small relay-interface, indicator, or signaling circuits that remain within 2W and 83mA. It is not positioned for larger 24V devices that need more current than this output provides.
Is the IRM-02-24 suitable for outdoor or washdown environments?
No outdoor or washdown rating is listed for this model. The published operating range is -30°C to +85°C with load derating per the derating curve, and the miniature encapsulated PCB-mount style is better suited to protected indoor equipment enclosures.
