Details
Meanwell DDR-120D-12 is a 120W DIN Rail type DC-DC converter with 12V10A0-10A120W15A180W (3sec.)50mVp-p9-14V. The model features easy installation, ultra slim width (32mm), and 2:1 wide input voltage. At the same time, DDR-120D-12 is designed fanless, and could work under -40~+70 ℃ wide operating temperature, 4KVdc I/O isolation, 150% peak load, adjustable output voltage and full protective functions.
In addition, this series of models has input options: 67.2~154Vdc, and various output options: 12V/24V/48V. The item could 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.
