Details
Meanwell DDR-240B Series is a 240W DIN Rail type DC-DC converter. The product adopts ultra-thin rail type chassis design. The main features include easy installation of hanging rails, a face width of only 40mm, which can greatly reduce the lack of space on the system end rail (TS-35/7.5 or 15), 2:1 wide voltage input, 4000VDC input/output isolation (with reinforced insulation), -40~+70°C operating temperature, and 150% peak load capacity. Additionally, DDR-240B can be paralleled to 960W (3+1 units), and withstands 5G resistance... etc. The design passes IEC62368-1/EN55032, EAC TP TC004 and railway EN50155 regulations certification, which can be used for industrial&railway control, security control, communication system and other fields.
What's more, this series of models has input options: 16.8~33.6V and two output options: 24V/48V. Suitable applications include to DC buck/boost regulator, increasing system insulation level and voltage drop compensation along cable...etc.
