RP12-AR
Description
12 Watt
1“ x 1“
Single and Dual
Output
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 class A 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.
