Converter series targets railway applications

The PMDS / PCMDS30 primary switched dc/dc converters series is designed for automotive and railway applications. The converters operate according to the current source push-pull principle and work with a frequency of 70 and 140 kHz.

The dc/dc converters use input voltages of 14.1 to 154 Vdc and output voltages of 5.1 12, 24 or 48 Vdc. The converters need no ground load and are short-circuit protected by primary and secondary power limitation. Additional features include reverse polarity protection and active input current limiting. The converters are maintenance free and vacuum encapsulated.
