Communications Applications No Longer Need Isolated Bus Converters

Communications Applications No Longer Need Isolated Bus Converters

Communications infrastructure equipment has traditionally used lead-acid batteries as a backup supply, which requires the batteries to power a positive referenced 48 V distribution system to avoid corrosion (cathodic protection). As this -48 V supply is used to power +48 V electronics, isolation between the batteries and the communication electronics is required. So the use of isolated bus converters became standard practice in these applications. With modern communications systems merging with server technology, and the communication portion moving from electrical to optical systems, today’s equipment can use negative referenced+48 V backup, meaning isolation is...

Robert Gendron Explains Why 48 V is the New 12 V in this On-Demand Webinar

Power system designers in a variety of applications, including telecoms, data centers, automotive, industrial, lighting and aerospace, have long relied on a 12 V intermediate (or hub) bus to distribute electrical power. With increasing demands for higher output powers in smaller spaces, and the need to improve efficiency, 12 V is rapidly being replaced with 48 V. By moving to a higher voltage, engineers reduce the I2R loss in cabling, improving power efficiency. The smaller, lighter cabling is also cheaper, offers easier routing of power, and enables further energy savings, particularly in transportation applications where weight...
