Information on the MEAN WELL IRM-90-48

The MEAN WELL IRM-90-48 is a high-voltage 48V output miniature AC-DC module, specifically engineered for PCB mounting in sophisticated industrial and automation environments. This 90W power solution is distinguished by its compact 3.43" x 2.05" footprint, allowing it to be integrated directly onto the motherboards of electronic instruments without the need for bulky chassis mounts. The unit is encased in a 94V-0 flame retardant plastic housing and fully encapsulated with silicone, which serves the dual purpose of enhancing thermal management and providing superior vibration resistance up to 5G. This ruggedized construction ensures that the internal components remain shielded from dust and moisture, maintaining long-term stability in harsh factory conditions.

Technically, the IRM-90-48 excels in efficiency and safety compliance, offering a high efficiency rating of 93% and an ultra-low no-load power consumption of less than 0.3W. These features make it an ideal "green" power module that meets strict worldwide energy regulations. It is designed as a Class II device, meaning it operates safely without a functional ground pin, and includes integrated EMI filtering to comply with BS EN/EN55032 Class B standards. Furthermore, the unit is rated for Overvoltage Category III (OVC III), making it suitable for industrial electrical equipment connected to building installations. With a wide universal input range of 80 to 305Vac and the ability to operate at altitudes up to 4000 meters, it provides a reliable and versatile power source for global industrial applications.
