The new primary switched DC/DC converters with 250 W and 400 W output power of MTM Power GmbH are especially designed for automotive applications. They operate according to the push-pull principle, i. e. the input dc-voltage is chopped by two push-pull working transistors with a frequency of approx. 60 kHz. With the help of a transformer and a secondary linear choke, a galvanically isolated output voltage (12 V or 24 V) is produced which is adjusted by pulse-width modulation according to the current mode principle. The series PCMD250W and PCMD400W are available with input voltages of 24 VDC (16,8…36 VDC), 80 VDC (50…150 VDC) or 110 VDC (66…154 VDC) and can be connected via screw connectors. The dimensions are 150 x 86 x 55 mm (L x W x H). Due to this compact design, they are also suitable for applications where only little space is available. The converters need no ground load, are maintenance free and short-circuit protected by primary and secondary power limitation. They are vacuum potted and prepared for the use in devices with Protection Class. As an option, they are available for the use in railway applications. Further features are a mechanically and electrically rugged design using SMD-technology and an automatic piece-by-piece test.
