## DESCRIPTION The RAC15-K/480 series AC/DC modules with ultra-wide input range of 100-480VAC are specially designed for harsh industrial conditions of overvoltage category OVC III and pollution degree PD3 in both single-phase and phase-to-phase power connections of class II. These power supplies are capable of operating over a wide temperature range of -40° to 90°C (up to 60°C without derating) by just adding an external fuse, and offer LPS limited outputs with continuous overcurrent protection and emission class B EMC compliance in potential free configuration of the load. These silicone-free encapsulated modules are built extremely compact to fit on printed circuit boards without compromising board area. Global safety certifications ensure fast time-tomarket when integrated into applications for markets such as Smart Grid, Smart Metering, Renewable Energy;Sensors and actuators or IoT applications. If the coverage of nominal input voltage up to 400VAC is sufficient you may also like RAC20NE-K/277/400 series in the same footprint and pinning pattern |SELECTION GUIDE(CONSTANT VOLTAGE OPERATION)|SELECTION GUIDE(CONSTANT VOLTAGE OPERATION)||||| |---|---|---|---|---|---| |Part|Input Voltage|Output|Output Current|Efficiency(1)|Output Power| |Number|Range|Voltage|nom.|typ.|continuous| ||[VAC]|[VDC]|[mA]|[%]|[W]| |RAC15-05SK/480|85-528|5|3000|86|15| |RAC15-12SK/480|85-528|12|1250|84|15| |RAC15-15SK/480|85-528|15|1000|85|15| |RAC15-24SK/480|85-528|24|625|87|15| Note1: Is tested at 230VAC input and constant resistive load at +25°C ambient copyright © RECOM Power GmbH, all rights reserved www.recom-power.com Rev. 2-2025 Page 1 Technical Data Sheet RAC15-K/480 Series ◊ AC/DC Power Supply 15W ◊ Input: 100V-480VAC **AC/DC Converter** Model Numbering ## - RAC15 _K/480 nom.
