The ERM100 and ERM150 are compact quarter-brick DC-DC converters optimized for rail and mass transportation applications.

The ERM100 and ERM150 series are compact quarter-brick, fully encapsulated 100 W and 150 W DC/DC modules optimized for rail and mass transportation applications. The ERM100 and ERM150 quarter brick modules comply with multiple industry standards and provide reliable, high-efficiency solutions for rail system designers. Both converters have a European Railway Standard EN50155 compliant input voltage range of 36 to 160 Vdc. The modules have an efficiency of up to 91.5% and operate with a fixed switching frequency and deliver a single, continuous power output.

The ERM100 and ERM150 have no minimum load requirement and exhibit low ripple and noise characteristics. A baseplate that is optimized for contact cooling simplifies thermal management, while a heatsink version is available for designs requiring more stringent heat management.
