Brand: MEAN WELL
SKU: SD-350B-48

MEAN WELL SD-350B-48 enclosed DC-DC converter, 19-36VDC input to a regulated 48VDC/7.3A output, rated at up to 350W.

The MEAN WELL SD-350B-48 is an enclosed, chassis-mount DC-DC converter that steps a nominal 24VDC input (accepting a 19 to 36VDC range) up to a regulated 48VDC output at up to 7.3A, for a rated output of 350.4W. Forced-air cooling is provided by a built-in DC fan, and the unit includes 1500VAC input-to-output isolation.

Protection features include short-circuit, overload and overvoltage protection, and the converter is rated for operation across -20C to +60C ambient. This class of DC-DC converter is commonly used in telecom and industrial power systems to derive a stable 48VDC rail from a lower-voltage DC source, such as a vehicle or standalone battery supply, for powering 48V-rail equipment.

This converter suits telecom and industrial installations needing a regulated 48V DC-DC power stage. Tech-Star (UK-based, shipped worldwide) checks every unit before it ships. Get in touch to confirm compatibility with your system.
