MTM Power Launches New Converter Series

PMDS/PCMDS30

Railway power supplier MTM Power has launched PMDS/PCMDS30, a new series of primary switched DC/DC converters, which is especially designed for automotive and railway applications.

The converters operate according to the current source push-pull principle and work with a frequency of 70/140kHz. Advantages of this switching topology are the wide input voltages with constant efficiency, transformer with good coupling and low leakage inductance, as well as its usability for direct control of the secondary synchronously detection.

The PMDS/PCMDS30 cover an input voltage of 14.4V DC to 154V DC with only two different nominal voltages and are available with an output voltage of 5.1V, 12V, 24V or 48V with 30W. The converters need no ground load and are short-circuit protected by primary and secondary power limitation.

Further features are reverse-polarity protection in connection with an active input current limiting. Depending on the application, the converters are available for either print or chassis mounting. The converters are maintenance-free, vacuum-encapsulated and prepared for use in surge protection Class II-type devices. They show a mechanically and electrically rugged design using SMD-technology and undergo an automatic piece-by-piece test.
