## DESCRIPTION The industry’s most compact integrated 6-watt AC/DC power supply series RACM06E is based on a 1”x1” footprint and fits into a low profile of just 17mm. Multiple international safety certifications to industrial, medical, and household standards ease implementation into a wide range of applications for direct connections to worldwide mains input voltage conditions to OVC III and without limitation to operating altitudes of up to 5000m. Even though it is a cost-efficient construction the thermally optimized design has safety rating for full load output power from -40°C up to 60°C with some derating continuing up 90°C. Internal EMI Filter supports compliance to EN55032 class “B” in floating output configurations without any need for additional filter components. |SELECTION GUIDE|||||| |---|---|---|---|---|---| |Part|Input Voltage|Output Voltage|Output Current|Efficiency(1)|Output Power| |Number|Range|nom.|max.|typ.|max.| ||[VAC]|[VDC]|[mA]|[%]|[W]| |RACM06E-3.3SK/277|80-305|3.3|1818|73|6| |RACM06E-05SK/277|80-305|5|1200|77|6| |RACM06E-12SK/277|80-305|12|500|82|6| |RACM06E-15SK/277|80-305|15|400|83|6| |RACM06E-18SK/277|80-305|18|333|82|6| |RACM06E-24SK/277|80-305|24|250|83|6| Note1: Efficiency is tested at nominal input (230VAC) and full load at +25°C ambient copyright © RECOM Power GmbH, all rights reserved www.recom-power.com Rev. 2-2024 Page 1 Technical Data Sheet **AC/DC Converter** ## RACM06E-K/277 Series ◊ AC-DC Power Supply ## 6W ◊ Input: 100V-277VAC |BASIC CHARACTERISTICS (measured @ TAMB= 25°C, nom.
