The RP12-AR series DC/DC converters are designed for railway rolling stock applications with an 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 filter network and offer single or dual outputs from 3.3V up to +/-24V. The high efficiency permits an ambient temperature range from -40°C to +85°C without derating, forced cooling or the need for heatsinks. The RP12-AR series feature UVLO, OVP, SCP 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.
