Description
IRM-90 is a 90W miniature (875229.5mm) AC-DC PCB-mount 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 80~305VAC. The 94V-0 flame
retardant plastic case and potted with silicone enhance the heat dissipation
and meet the anti-vibration demand up to 2~5G anti-vibration by model;
moreover, it provides the fundamental resistance to dust and moisture. With
the high efficiency up to 93% and the extremely low no-load power consumption
below 0.3W, IRM-90 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 from electromagnetic interference. In
addition to the PCB mounting style model, IRM-90 series also offers the screw
terminal style model (ST).

****NOTE**|
- All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
- 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
- Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1μf & 4?μf parallel capacitor.
- Tolerance : includes set up tolerance, line regulation and load regulation.
- Derating may be needed under low input voltages. Please check the derating curve for more details.
- Leakage current was measured from primary input to DC output.
- The ambient temperature derating of 3.5℃/1000m with finless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
- The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on http://www.meanwell.com)
