36-185VDC input voltage range (max.) Features 3kVDC/1 minute isolation DC/DC Converter -40C to +85C ambient without derating EN50155 certified, EN45545-2 compliant, CE marked Regulated Efficiency up to 90% Converter Compact 1x1 case size RP12-AR Description 12 Watt The RP12-AR series DC/DC converters are designed for railway rolling stock applications with an 1 x 1 extra wide continuous input voltage range of 36-160VDC (185VDC for 1s), making them suitable for 48V, 72V, 96V and 110VDC railway systems, but they are also suitable for non-railway high voltage battery applications. They have a built-in class A filter network and offer single or dual outputs from Single and Dual 3.3V up to +/-24V. The high efficiency permits an ambient temperature range from -40C to +85C without derating, forced cooling or the need for heatsinks. The RP12-AR series feature UVLO, OVP, SCP Output and OLP. This makes them ideal for many harsh railway and industrial applications such as powering IoT sensors, battery management systems or electric fork-lift trucks. The RP12-AR is available in an industry standard 1 x 1 package and comes with a 3 year warranty. Selection Guide (1) Part Input Output Output Efficiency Max.
