Description
The Bel V7PC-04C series modules are non-isolated, boost DC/DC power converters that operate from a nominal 3.3V source. These converters provide an output voltage of 5V and are packaged in an industry standard single-in-line footprint with 4A maximum output. Standard features include remote on/off, over current and short circuit protection. A version of this converter is also available without remote on/off. These products may be used almost anywhere 5V is required and a 3.3V source is available. Typical applications include file servers, routers, line cards and other computing and communications equipment.
Applications
• • • Telecommunications Networking Computers and peripherals
