DDR is a series of DC/DC power supply units for DIN-rail mounting. Their characteristic feature is a particularly slim enclosure profile, which minimizes space occupied in a control cabinet. Furthermore, the new power supply units from MEAN WELL are protected against overload, overvoltage, short circuit, reverse polarity, and insufficient input voltage. An important feature of the DDR series is the reinforced I/O insulation of 4kV.
The DDR-120 version is compliant with the EN50155 and EN45545-2 railway industry standards.
