Information on the MEAN WELL IRM-90-12

The MEAN WELL IRM-90-12 is a high-density, 90W miniature AC-DC module designed for direct PCB mounting, offering a sophisticated power solution for space-constrained industrial and electronic applications. Its compact 3.43" x 2.05" footprint makes it an ideal choice for modern automated systems where board real estate is at a premium. One of its standout features is the fully encapsulated 94V-0 flame retardant case, which is potted with silicone to provide superior heat dissipation and robust anti-vibration resistance up to 5G. This rugged design ensures the unit remains protected against dust and moisture, making it highly reliable in demanding factory environments or handheld electronic devices.

Efficiency and safety are central to the IRM-90 series design, boasting an efficiency rating of up to 92.5% and an ultra-low no-load power consumption of less than 0.3W. This allows the power supply to meet strict global green energy regulations while maintaining a low thermal profile. Furthermore, the unit is engineered as a Class II isolation device, meaning it requires no protective earth (FG pin), and it is rated for Overvoltage Category III (OVC III). This rating is particularly beneficial for industrial equipment connected directly to the building installation, as it provides a higher level of protection against electrical transients. With its wide input range of 80 to 305Vac and the ability to operate at altitudes up to 4000 meters, the IRM-90-12 is a versatile and durable power module for global industrial deployment.
