Details
Meanwell DDR-120A-48 is a 120W DIN Rail type DC-DC converter with 48V2.1A0-2.1A100.8W3.15A150W (3sec.)50mVp-p48-56V. The model outstands easy installation, ultra slim width (32mm), and 2:1 wide input voltage. In addition, DDR-120A-48 is designed fanless, and works under -40~+70 ℃ wide operating temperature, 4KVdc I/O isolation, 150% peak load, adjustable output voltage and full protective functions.
Apart from them, 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. The unit 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.
