ABSOPULSE 250W Convection Cooled Railway Converters for On-board Rolling Stock Applications

The LTH 65R-F3-HSA series of heavy-duty, railway quality DC-DC converters are designed to float charge hold-up batteries for on-board rolling stock electrical equipment.

The units are also suitable for a broad range of other transportation and industrial applications. The converters operate from a 12Vdc (10.5-16V) input and deliver 24V, 48V or 125Vdc and their corresponding float charges. Custom input / output values are available on request. An optional built-in redundancy diode allows for paralleling and N+1 operation or back-up battery connection.

The railway converters are cooled by a heatsink assembly block with fins attached to the under-surface of the unit. The heatsink assembly also allows for mounting on uneven and thermally non-conductive surfaces. The units are rated for operation over a -25°C to 55°C temperature range for full. Wider temperature ranges are available on request.

The LTH 65R-F3-HSA converters meet the requirements of EN50155 for electronic equipment used on railway rolling stock. They are equipped with heavy filtering on the input and output and comply with EN 50121-3-2. The units also meet the requirements of EN 50121-4, EN 61000-4-2, EN 61000-4-3, EN 61000-4-4, and EN 61000-4-6.
