## DESCRIPTION The economy itemized RAC10E-K series are extra compact 1.8”x1” encapsulated PCB-mount AC/DC modules with a wide input operating range of 85 to 305Vac and come with international safety certifications for industrial, AV and ITE as well as household standards. These Power Supply modules with certifications to overvoltage category OVC III environments operate in a temperature range of -40°C to +90°C with up to 5000m operating altitude and offer fully protected single outputs as well as EMC class B compliance without the need of any external components. |SELECTION GUIDE||||| |---|---|---|---|---| |Part|Input Voltage|Output Voltage|Output Current|Efficiency| |Number|Range|nom.|max.|typ.(1)| ||[VAC]|[VDC]|[mA]|[%]| |RAC10E-3.3SK/277|85-305|3.3|2500|76| |RAC10E-05SK/277|85-305|5|2000|80| |RAC10E-12SK/277|85-305|12|833|83| |RAC10E-15SK/277|85-305|15|666|83| |RAC10E-24SK/277|85-305|24|416|84| Note1: Efficiency is tested at nominal input (230VAC) and full load at +25°C ambient ## MODEL NUMBERING ## - RAC10 E SK/277 nom.
