Mean Well DDRH-120-12 Ultra Wide Input DC-DC Converter, 100.8W 12V

The DDRH-120 is a 120W high-reliability ultra-wide input DIN Rail DC-DC converter engineered for photovoltaic, renewable energy storage, and high-voltage industrial systems. Its 250~1500Vdc input range covers high-voltage DC bus and battery string sources, while 4KVac reinforced I/O isolation ensures clean, noise-free power conversion. Featuring fanless free air convection cooling and a DC OK relay output, the DDRH-120 reliably operates across a -40~+80℃ temperature range.
