Overview
IRM-05-12 is the 12V output model of this series: rated current 0.42A, rated power 5.04W, typical efficiency 75%.
IRM-05 is a 5W miniature (45.7*25.4*21.5mm) 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 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 0.1W, IRM-05 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.

Test conditions and notes6
- 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. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
- 5. 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).
- 6. 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
What output does the Mean Well IRM-05-12 provide?
The IRM-05-12 is a 12V AC/DC switching power supply rated for 0.42A output current. Its maximum output power is 5.04W, making it suitable for low-power embedded and PCB-based applications.
What input voltage range does the IRM-05-12 support?
This model supports a universal input range of 85 to 305VAC and 120 to 430VDC. That wide input range makes it practical for equipment intended for use across multiple regions or varying power environments.
What protection features are included in the IRM-05-12?
The IRM-05-12 includes short circuit, overload, and over voltage protection. The overload protection range is listed at 115% to 260% of rated output power, and over voltage protection is 13.8 to 16.2V.
Is the Mean Well IRM-05-12 a good fit for compact embedded designs?
Yes, this model is designed for space-constrained applications with a compact encapsulated form factor measuring 45.7 x 25.4 x 21.5 mm. It is a PCB-mount module potted with silicone in a 94V-0 flame-retardant plastic case, with a Class II (no FG pin) design.
Can the IRM-05-12 be used in demanding industrial environments?
It is designed for reliable operation with free air convection cooling and 5G vibration resistance. The listed working temperature range is -30 to +85°C with output derating per the derating curve, so buyers should confirm their operating conditions stay within that specification.
How does the IRM-05-12 compare with larger enclosed power supplies?
The IRM-05-12 is intended for low-power applications where compact size and board-level integration matter more than higher wattage capacity. Compared with larger enclosed supplies, it offers only 5.04W output but provides a much smaller encapsulated package for tight internal spaces.
What compliance and safety approvals are listed for the IRM-05-12?
The product is listed with UL62368-1, TUV BS EN/EN62368-1 and IEC/EN61558-1/-2-16 safety approvals, among others. EMC standards in the specification include EN55032 Class B, EN55035, EN61000-6-2 and EN61000-3-2, -3-3, -4-2, -4-3, -4-4, -4-5, -4-6, -4-8, and -4-11.
