IRM-90 - 90W AC-DC PCB-Mount Green Power Module

In order to fulfil the higher wattage demands from the market, MEAN WELL have introduced the 90W IRM-90 Series, which can be directly mounted and soldered onto the PCB. Additionally, the IRM-90 Series screw terminal type can offer alternative mounting and wiring options.



IRM-90 is a 90W miniature 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 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 93% and the extremely low no-load power consumption below 0.21W, IRM-90 Series fulfils the worldwide regulation for the low power consumption requirement for electronics. 

The entire IRM-90 Series is a Class II design, 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. 

In addition to the PCB mounting style model, the IRM-90 Series also offers the screw terminal style model.
