The RAC05-K/277 series are multipurpose 5 watt AC/DC power supplies for enhanced mains
input conditions rated to overvoltage category OVC III from 90VAC up to 305VAC with an extra wide
operating temperature range from -40°C to +90°C. These modules are designed to supply worldwide
applications in automation, Industry 4.0, IoT, household and smart buildings. For worldwide use they
come with international safety certifications for industrial, domestic and ITE as well as household
standards. With both PCB-mount and wired packages, fully protected outputs, and EMC class B
emissions compliance without any external components, these are the easiest to use modular power
solutions in the industry.
