Triple-output DC/DC Converter Suits Railway, Mobile and other Severe Environments

All outputs are fully regulated, floating and isolated from each other; it has 1000V isolation between the outputs and 3000Vdc input to output isolation. Nominal input voltages are 24Vdc (15 - 34V range), 48Vdc (29 - 67V range), 72Vdc (43 – 101V range), 96Vdc (58 – 135V range) or 110Vdc (66 - 154V range), in compliance with EN50155. Other input and output values are available on request.

This series is suitable for a wide range of railway applications. It meets all relevant standards for electronic equipment used on railway rolling stock including EN50155, EN50121-3-2 conducted and radiated EMI, EN55022 Class B, and EN61000 immunity.

The DCW 153R series operates at full specification over a -25oC to +55oC cold-plate temperature range. Cooling is by conduction to customer heat sink or chassis and by natural convection. This series is housed in a compact, vented enclosure that measures 114 x 58 x 256 mm. A green “Output ON” LED is visible through the cooling slots.

Environmental protection includes full ruggdizing and conformal coating, and the series meets EN61373/IEC61373 shock and vibration standards. Full electronic protection, large design headroom, and the exclusive use of components with established reliability result in a high MTBF.
