## DESCRIPTION The compact 3 Watt AC/DC power supplies series RAC03-K/SMT boast an optimized design tailored for JEDEC-reflow solder processes. With a mere 1in² footprint, these units facilitate automated production, ensuring a shock and vibration-resistant PCBA. The fully integrated modules eliminate the need for external components in floating load configurations, providing safety-rated performance at altitudes up to 6000m. Operating seamlessly in temperatures ranging from -40 to +80°C, and offering a continuous 3-Watt output power from -25 to +60°C, these power supplies are engineered for reliability. Compliant with international standards, including EN/IEC/UL62368, EN60335, and IEC61558, they are an ideal solution for a diverse range of applications from IoT to industrial automation, driving sensors, household and monitoring devices, as well as housekeeping auxiliary power supplies, these power units are well-suited for domestic use. |SELECTION GUIDE||||| |---|---|---|---|---| |Part|Input Voltage|Output Voltage|Output Current|Efficiency(1)| |Number|Range|nom.|max.|typ.| ||[VAC]|[VDC]|[mA]|[%]| |RAC03-3.3SK/SMT-R|85-265|3.3|900|69| |RAC03-05SK/SMT-R|85-265|5|600|74| |RAC03-12SK/SMT-R|85-265|12|250|78| |RAC03-15SK/SMT-R|85-265|15|200|75| |RAC03-18SK/SMT-R|85-265|18|170|78| |RAC03-24SK/SMT-R|85-265|24|125|77| Note1: Efficiency is tested at nominal input (230VAC) and constant resistive load at +25°C ambient copyright © RECOM Power GmbH, all rights reserved www.recom-power.com PRELIMINARY Page 1 Technical Data Sheet RAC03-K/SMT Series ◊ AC/DC Power Supply 3W ◊ Input: 100V-240VAC **AC/DC Converter** MODEL NUMBERINGSpecifications (measured @ Ta= 25°C, nom.
