Recom’s RP12-AR DC/DC converter series, measuring just 1”x1”, operate with 90% efficiency and up to +88°C ambient at full load.

The 12W units are designed for railway rolling stock applications, but 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.
