DC / DC power supply:
for railway applications with wide input range MTM Power
50 W

MTM Power GmbH, the specialist for high quality power supplies, has designed the DC/DC converter series SMM50 for the use in vehicles, particularly for railway applications. These converters have an output power of 50 watts and are suitable for the stationary use as well as for the mobile use acc. to EN 50 155. The nominal input voltages are 24 VDC ((14,4…50,4 VDC), 48 VDC (28,8…100,8 VDC) and 110 VDC (43,2…154 VDC) and 230 VAC (85…264 VAC). 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 acc. to IEC 68 T.2-27, high efficiency of 79...89 % and reverse polarity protection at the input. The devices are prepared for the use in 19" racks and have a H11 connector acc. to DIN 41 612. The dimensions are 173,0 x 38,7 x 111,2 mm or 177,0 x 40,2 x 128,4 mm (length x width x height). The series SMM50 needs no ground load, is short circuit protected and has various monitoring and protection systems.
