120-Watt DIN Rail Mount Railway DC to DC Converter

DDR-120

Description

The MEAN WELL DDR-120 series DC to DC converters have been designed to comply with standards EN50155 and EN45545-2, so they are suitable for use on locomotives and passenger trains or trams. They are only 32mm wide and have a wide 2:1 input voltage range. There are four input options:

9~18 VDC
16.8~33.6 VDC
33.6~67.2 VDC
67.2 ~ 154VDC

The output voltage can be adjusted via the built-in potentiometer and these DC converters have a 150% peak load capacity. For safety the DDR-120 DC converters have 4KVdc reinforced input / output isolation.
