It has been announced that RECOM’s railway portfolio has been further extended with the new RP12-AR DC/DC converter series. These compact 12W one by one inch modules operate with 90% efficiency and up to +88°C ambient at full load. The RP12-AR series DC/DC converters are designed for railway rolling stock applications, but they are also suitable for non-railway high-voltage battery applications. 

Their 5:1 input voltage range of 36-160VDC (185VDC for 1s) allows for all-in-one solutions for 48V, 72V, 96V and 110VDC railway systems. They have a built-in class A filter network and offer single or dual outputs from 3.3V up to +/-24V. The high efficiency of up to 90% enables these modules to be operated at a wide ambient temperature range from -40°C to +88°C without derating.

Neither forced cooling nor additional heatsinks are required when operating them at full load. The RP12-AR series feature UVLO, OVP, SCP, and OLP, which makes them ideal for many harsh railway and industrial applications such as powering IoT sensors, battery management systems or electric fork-lift trucks.

They are CE marked and come with a three year warranty. Samples and OEM pricing are available from all authorised distributors or directly from RECOM.
