 Introduction
DDR series is a DIN Rail type DC-DC converter with main features including DIN rail-type easy installation, ultra
slim width, 2:1 wide input voltage, fanless design, -40~+70℃ wide operating temperature, 150% peak load,
adjustable output voltage and full protective functions.
This series of models has various input options: 9~18V / 16.8~33.6V / 33.6~67.2V / 67.2~154V and various output
options: 12V / 24V / 48V and can be used for industrial & railway control, security control, communication system
and other fields. Suitable applications include DC buck/boost regulator, increasing system insulation level and
voltage drop compensation along cable...etc.
