The 48V(30V60V) to 19V 10A Step Down DC DC Converter is a buck converter designed to take a DC input in the range of 30 to 60 volts (nominal 48V) and deliver a stable 19V output at up to 10A. It enables powering 19V devices from higher voltage sources and is suitable for applications requiring a reliable, singlesource 19V supply from a 48V or wider range DC bus. Key benefits Wide input range supports 30–60V sources, including 48V systems. Delivers 19V at up to 10A (maximum 190W), enabling 19V devices to operate from a higher voltage supply. Simplifies power design by centralizing conversion and reducing the need for multiple adapters. Facilitates straightforward integration with 19V devices and equipment. Supports organized and consolidated power distribution in systems that use a 48V or higher DC bus. Key attributes Functionality: Stepdown DCDC converter (buck) from 30–60V input to 19V output. Output: 19V at up to 10A (190W maximum). Input: 30–60V DC (nominal 48V). Compatibility: Suitable for devices that require a 19V DC input; ensure connectors match. Size and materials: Not specified in the product title; exact dimensions and enclosure material are not provided here.
