A general feature of all the converters of the RACxx-K series is that they are capable of accepting the universal input range. However, RECOM anticipated a need for industrial-grade low power AC/DC converters for use in IIoT applications and developed modules ranging in 3.5W to 10W that are able accept up to 277V_AC. They also developed the RAC05-K/480 which can accept up to 480V_AC. These products were designed to be complete switching solutions. They come pre-certified to international safety standards, feature an internal Class B EMC filter, and can operate through a wide temperature range, including start-up capabilities at -40°C.
