What is 48VDC power supply?
In fact, -48VDC allows telecom operators to use 12-volt lead-acid batteries wired in series to act as a backup power source in the event of a power failure. Negative 48VDC (-48V), or positive grounded, was selected for use by Bell when it was found to be superior to positive voltage.
Why 48v is used in telecom?
The reason Bell selected -48VDC is because it provides enough in power to support a signal, but not enough to be dangerous. In fact, -48VDC allows telecom operators to use 12-volt lead-acid batteries wired in series to act as a backup power source in the event of a power failure.
What is negative 48V?
Negative 48VDC (-48V), or positive grounded, was selected for use by Bell when it was found to be superior to positive voltage. It prevents electrochemical reactions from destroying buried copper cables and rendering them useless if they happen to get wet.
What is DC-to-DC power supply?
A DC to DC power supply converts a direct current (DC) input supply to a DC output supply typically at a different voltage level. There are many different types of DC power supply converters available, which are grouped into three categories: linear DC power supplies, switching DC power supplies, and switching flyback.
What is the best DC-to-DC converter?

Why is a 48 volt power supply negative?
Why 48V is used in telecom?
Why the most of telecom equipments use the -48V DC for their input voltage rather than the 110/220 V AC? -48V DC has been a traditional voltage for telephone applications. Large battery backups are used to guarantee that telecom equipments can get constant power no matter if mains power fails.
