Model Encoding
Description
IRM-20 is a 20W miniature (52.4*27.2*24mm) 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~ VAC. The flame retardant plastic case 305 94V-0 and
the fully-potted 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 85% and the extremely low no-load power consumption below 0.1W, IRM-20
series fulfills the worldwide regulation for the low power consumption requirement for electronics. The entire
series is a Class design (no FG pin), incorporating the built-in EMI filtering components, enabling the
compliance with EN55032 Class B; the supreme EMC features keep the end electronic units from
electromagnetic interference.

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 0.1uf & 47uf 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.
