ABSOPULSE’s RWY 200-HSA-P2 series fully encapsulated railway quality DC-DC converters with pure convection cooling deliver up to 200W. The units meet the requirements of EN 50155 for electronic equipment used on railway rolling stock. The units are cooled by a heatsink assembly attached to their under-surface. This enables operation over a -40 to +55^oC temperature range without derating. Wider temperature ranges are available on request.

The heatsink assembly can be mounted to a chassis or DIN-rail. The chassis-mounted option is suitable for applications in which a suitable heatsinking surface is not available and only convection cooling will suffice. The heatsink assembly is also suitable for mounting on thermally non-conductive surfaces such as wood, plastic and brick walls.
