250W Convection cooled railway DC-DC converters
Featured Product from ABSOPULSE Electronics Ltd.
The LTH 65R-F3-HSA series of heavy-duty, railway quality DC-DC converters are designed to float charge hold-up batteries for onboard 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. Additional cooling is achieved by natural convection through the cooling slots. The heatsink assembly also allows for mounting on uneven and thermally non-conductive surfaces. A DIN-rail mounting option is available. The units are rated for operation over a -25°C to +55°C temperature range for full specification without derating required. 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.
