12W Railway DC-DCs Deliver Full Power up to 88°C Ambient

RECOM has added the new RP12-AR dc-dc converter series to its railway portfolio. These compact 12W, 1in x 1in modules operate with 90% efficiency and up to +88°C ambient at full load.

The RP12-AR series railway 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 36Vdc to 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 provide single or dual outputs from 3.3V up to ±24V. The high efficiency of up to 90% enables these modules to be operated at an 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 suitable 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 3-year warranty. Samples and OEM pricing are available from all authorized distributors or directly from RECOM.
