Details
Meanwell DDR-120B-48 is a 120W DIN Rail type DC-DC converter with 48V2.5A0-2.5A120W3.75A180W (3sec.)50mVp-p48-56V. The item outstands easy installation, ultra slim width (32mm), and 2:1 wide input voltage. Additionally, DDR-120B-48 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.
Moreover, this series of models has input options:16.8~33.6V, and various output options: 12V/24V/48V. The model 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.
