Information on the MEAN WELL IRM-90-15ST

The MEAN WELL IRM-90-15ST is the specialized chassis mount version of the 90W miniature AC-DC power module series, featuring integrated screw terminals for easy and secure wiring. This "ST" model is specifically designed for industrial applications where components must be mounted directly to a panel or chassis rather than soldered to a PCB. The unit is fully encapsulated within a plastic case that meets 94V-0 flame retardant safety standards, providing an airtight shield against dust and moisture. Its fanless design relies on free air convection for cooling, ensuring silent operation and a high degree of mechanical reliability in environments prone to vibration or physical stress.

From an electrical standpoint, the IRM-90-15ST is highly optimized, delivering 93% efficiency and maintaining a no-load power consumption of less than 0.3W. This energy-efficient profile makes it an ideal choice for green industrial automation and handheld electronic devices. Security is a paramount feature, as the module is classified as a Class II isolation device and carries the Overvoltage Category III (OVC III) rating. This enables the power supply to be utilized in demanding industrial electrical equipment that requires direct connection to the building’s distribution network. With a wide input range of 80 to 305Vac and certification for altitudes up to 4000 meters, this 15V power module is a robust solution for global industrial infrastructure.
