This convention makes the entire telecom system more immune to corrosion and safer for individuals performing telecom maintenance. This negative polarity prevents metal ions from migrating from one metal element to another, which is the cause of rapid battery terminal and copper wire corrosion. Although many new telecom stations have become very compact, they remain backwards compatible in terms of being powered by V. This feature will remain a standard into the foreseeable future.
There are installations where power demand is modest and there is no room to accommodate 4 batteries to provide 48V emergency power. Our technical staff is well versed in these applications and can provide guidance in configuring and wiring. Please consult with us should you have any questions about system configurations. Configuration Defined Telecom and wireless networks typically operate on 48 volt DC power.
History Why is the positive side of the DC circuit connected to ground in telecom applications versus negative ground used, as used, in automotive and other industrial dc systems?
