6 FAQs about Solar Why do communication base stations use 48v power supply

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.

What power supply is used in a central office communication system?

Later, in order to be compatible with early equipment and reduce costs, the central office communication equipment still used -48V power supply. Likewise, with a negative power system, the positive ground is just a convention. It turns out that there is a saying that there are a lot of negative charges in the air.

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 voltage was used in the earliest communication network?

The earliest communication network used was the telephone network, and the telephones were powered by the telecommunications office. 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).
