DC-DC converters rated to IP65

3 March 2010 Power Electronics / Power Management

The primary switched DC-DC converters of MTM’s PCMDS150WK-IP65 range are specially designed for applications in vehicle and rail technology but are also suitable for use in industrial and telecommunication applications.

The push-pull topology enables a wide input voltage range – the 150 W converters are available for battery voltages of 24, 36, 48, 60, 72, 80, 96 and 110 V in accordance with EN 50 155.

With the help of a transformer and a secondary linear choke, a galvanically isolated output voltage of 24 V is produced which is adjusted by pulse-width modulation according to the current mode principle. The dimensions are 192 x 115 x 68 mm. The thermoselective vacuum encapsulation guarantees uniform heat dissipation within the modules as well as resistance against environmental influences such as shock, vibration and moisture. The converters measure 192 x 115 x 68 mm and are suitable for applications with protection degree IP65. They need no ground load and are short-circuit protected by primary and secondary power limiting.
