Description 3.5 Watt
The RAC3.5-K/277 series are multipurpose 3.5 watt AC/DC power supplies for enhanced mains input 3
LT conditions from 85VAC up to 305VAC with an extra wide operating temperature range from -40°C to Single ~
+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 Output
industrial, domestic and ITE as well as household standards. With fully protected outputs, as well as EMC
class B emissions compliance without any external components, these are the easiest to use modular
power solutions in the industry.
