## Features 

Regulated Converter 

• 1 inch² footprint for the tiniest 3 watt module • Standby mode optimized (Ecodesign Lot 6) • No load power consumption <150mW • Operating temperature range: -40°C to +80°C • Household IEC/EN60335 • EMC compliance without external components 

## **AC/DC Converter** 

## **RAC03-K** po 

Description The RAC03-K series are the smallest 3 watt solution on the market. In a compact 1in[2] footprint, these ~~Lo~~ modules deliver an output power of 3 watts from -40°C to 60°C and 2 watts up to 80°C. Despite such a high power density and small footprint, the RAC03-K series is a complete solution supporting Ecodesign Lot 6 standby mode operation for worldwide applications in automation, industry 4.0, IoT, household, and home automation. With an input voltage range from 85 to 264VAC and international safety certifications for industrial, domestic, ITE, and household applications, these are some of the most versatile power modules on the market. Due to their reinforced class II installation rating and their significantly wide margin to class B emissions compliance without external components, these are the easiest to use modular power solutions in the industry.
