Description
The Bel S7AH-07C and V7AH-07C modules are a series of non-isolated, step down DC/DC power converters that operate aged in a compact, overmolded package rated at 7A. Optional lead forming provides a vertical mount product for minimal footprint or a surface mount option for a very low profile. Standard features include remote on/off, over current and short circuit protection, and output voltage adjust. These products may be used almost anywhere low voltage silicon is employed and a 3.3V source is available. Typical applications include file servers, routers, line cards and other computing and communications equipment.
