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...

Bodo’s Power Features Vicor Article Explaining the Move to +48 V in Communications Systems

The latest issue of Bodo’s Power features an article written by Chester Firek, senior product marketing manager at Vicor, describing how telecoms and datacoms equipment manufacturers have migrated from -48 V to +48 V power systems, allowing them to take advantage of power components developed for other markets, particularly data center servers. In the past -48 V was selected because it reduced the vulnerability to corrosion caused by crude charge-control systems, humidity, and poor ventilation in the battery rooms of that era. With better environmental controls, power system designers can move...
