Absolutely Reliable: 19ft DC/DC Converters for Automotive – SMM50

MTM Power GmbH, the specialist for high quality power supplies, has designed the DC/DC converter series SMM50 for use in vehicles, particularly for railway applications. These converters have an output power of 50W and are suitable for stationary as well as mobile use according to EN 50 155.

The nominal input voltages are 24VDC (14.4VDC – 50.4 VDC), 48 VDC (28.8VDC -100.8VDC) and 110VDC (43.2VDC – 154VDC) and 230VAC (85VAC – 264VAC). Due to these input voltage ranges, the converters can be used in all on-board power systems. The output voltages are galvanically separated and are available as single, dual and triple versions. Further features are vibration and shock resistance according to IEC 68 T.2-27, high efficiency of 79% – 89% and reverse polarity protection at the input.

The devices are prepared for use in 19ft racks and have an H11 connector according to DIN 41 612. The dimensions (length x width x height) are 173mm x 38.7mm x 111.2mm (tubus panel) or 177mm x 40.2mm x 128.4mm (europac). The series SMM50 needs no ground load, is short circuit protected and has various monitoring and protection systems.
