Experts in individual power supplies MTM Power GmbH have designed the PCMDS60W series of DC / DC converters, used specifically for applications in rail and vehicle technology, with additional applciations in industrial and telecommunication applications.
These primary switched DC / DC converters are available with an output power of 60 Watts and operate according to the push-pull principle with a frequency of approx. 70 kHz. With the help of a transformer and a secondary linear choke, a galvanically isolated output voltage (5,2V, 12V, 15V, 24V or 48V) is produced which is adjusted by pulse-width modulation according to the current mode principle.
The converters are available with a wide input range for battery voltages of 24V, 36V, 48V, 60V, 72V, 96V and 110V acc. EN 50 155. The dimensions are 130mm x 69mm x 30mm (length x wide x height). Due to this flat design, the series PCMDS60W is also suitable for applications where only little space is available. They are connected via spring clamps, which meet the special requirements e. g. in railway applications as regards to vibration resistance and reduced time for wiring.
The converters need no ground load, are maintenance free and short-circuit protected by primary and secondary power limitation. Further features are a mechanically and electrically rugged design using SMD-technology and an automatic piece-by-piece test. They are vacuum potted (EP 1 987 708, US Patent No. 8,821,778 B2), prepared for the use in devices with Protection Class II and have to be mounted on a heat-dissipating surface for cooling.
Without any additional external components the PCMDS60 meet all functional and normative requirements of electronic equipment in railway applications acc. to EN 50 155, EN 50 121-3-2, EN 61 373 Cat 1, Cl. B. As a plug-and-play solution for sensitive electrical subsystems, the converters can be easily installed and operated in the field.
