EN50155-Slide5

The old EN50155 standard defined only four different operating temperature ranges. The new version increased that number to six, but tightens up on the way that the operating temperatures and the extended temperature limits during start-up are tested. All RECOM railway grade DC/DC converters can meet the most stringent operating temperature of OT6 /ST2 when used with a suitable heatsink.
