DC-DC converters for demanding environments

RECOM’s railway portfolio has been further increased with the new RP12-AR DC-DC converter series. These compact 12W 1”x1” modules function with 90% efficiency and up to +88C ambient at full load. The series is intended for railway rolling stock applications, but they are also fit for non-railway high-voltage battery applications. Their 5:1 input voltage range of 36-160VDC (185VDC for 1s) provides for all-in-one solutions for 48V, 72V, 96V and 110VDC railway systems. They have a built-in class A filter network and provide single or dual outputs from 3.3V up to +/-24V. The high efficiency of up to 90% allows these modules to be operated at a broad ambient temperature range from -40C to +88C without derating. Neither forced cooling or additional heatsinks are needed when operating them at full load. The series feature UVLO, OVP, SCP, and OLP, which makes them perfect for many harsh railway and industrial applications such as powering IoT sensors, battery management systems or electric fork-lift trucks.
