4 Frequently Asked Questions about "What does 48v power supply for communication base station mean "
Why do we use 48V power supply?
The choice of 48V was to maximize the distance between the user and the end office under the conditions at the time (36V is a safe voltage, and it is unsafe to exceed too much). Later, in order to be compatible with early equipment and reduce costs, the central office communication equipment still used -48V power supply.
Why do telecom networks use –48 V DC power?
Telecom and wireless networks typically operate on –48 V DC power, but why? The short story is that –48 V DC, also known as a positive-ground system, was selected because it provides enough power to support a telecom signal but is safer for the human body while doing telecom activities.
What is the operating voltage range for -48V system equipment?
For -48V system equipment, the required operating voltage range is -38.4V ~ 57.6V, but in fact we generally require the operating range -36V ~ -72V. The main consideration is that -48V system equipment must be compatible with –60V power supply system, which requires –48~-72V.
What are the applications of -48V DC telecommunications equipment?
Telecommunications equipment draws a lot of current and all of the wires and conductors are very large. Other applications for -48V DC include powering cell towers, local cable TV vaults, and legacy central offices of the various incumbent local exchange carriers (ILECS). Many of these ILECS have been bought back by AT&T.
