Schaffner FN2500 and FN2640 EMI/EMC Filters offer a DC to 60Hz operating frequency, 277VAC maximum operating voltage, and a UL 94V-0 flammability rating. These filters are developed to meet the specific needs of the growing robotics and data center markets, which have requirements in common that can be met by these EMC filters. FN2500 and FN2640 filters feature a 1U rack-mount design because many robotics, data center, and autonomous machine applications require power supplies to be mounted in 19″ rack cabinets. Schaffner FN2500 and FN2640 EMI/EMC Filters are built to fit and perform well in data center and audio and video equipment.
