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-10-12 provide?

The IRM-10-12 is a 12V AC/DC switching power supply rated for 0.85A output current. Its maximum power rating is 10.2W, making it suitable for low-power embedded and PCB-based applications that require a regulated 12V output.

What input voltage range does the IRM-10-12 support?

This model accepts a universal input range of 85 to 305VAC and also supports 120 to 430VDC input. That wide input range makes it useful for equipment intended for different mains regions without needing separate input-specific versions.

What kinds of applications is the IRM-10-12 typically used for?

The IRM-10-12 is designed for compact internal power conversion, soldered onto the PCB of embedded equipment where board space matters. Its miniature encapsulated form factor, free-air cooling, and low no-load power consumption make it a fit for industrial and commercial low-power electronics.

What protections are built into the Mean Well IRM-10-12?

This model includes short circuit, overload, and over voltage protection. The overload protection is listed at 115% to 190% of rated output power (hiccup mode, auto-recovery), and over voltage protection is listed at 13.8V to 16.2V, about 115% to 135% of rated output voltage.

How compact is the IRM-10-12 power supply?

The listed dimensions are 45.7 x 25.4 x 21.5 mm, and the product weight is 0.033 kg. That compact size helps when designing space-constrained products that still need an enclosed AC/DC power module.

Is the IRM-10-12 intended for reliability-focused applications?

Yes. The datasheet lists a 94V-0 flame-retardant plastic case potted with silicone, Class II isolation, and anti-vibration capability up to 5G, all of which support use in durability-focused equipment designs. It also carries a 3-year warranty.
