The RAC05-K was the first of the “K” series to be released. It features a small 1” x 1” footprint and (like many other of RECOMs AC/DCs) is certified to UL, IEC, and EN 62368-1. It has a minimal no load power consumption of 75mW and an output ripple which can be as low as 60mV peak-to-peak. It is an excellent option for IoT applications, such as security system applications.
