DC/DC Converters with 400 W

 

The primary switched DC/DC converters with 400 W output power of MTM Power®, the specialist for individual power supplies, 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 PCMD400W is available with input voltages of with 36 VDC, 72 VDC, 80 VDC and 110 VDC andcan be connected via screw connectors. The dimensions of the devices which are available in an aluminium case are 150 mm x 86 mm x 55 mm (length x width x height). 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, prepared for the use in devices with Protection Class II and fulfil the low voltage directive. 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. To ensure a smooth operation, it is necessary to mount the converters on a heat-dissipating surface.
