The RAC05-K/277 series are multipurpose 5 watt AC/DC power supplies for enhanced mains input
conditions 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.
