FAQs 6

Can a 48 volt DC power supply save a data center?

(Fig. 5) As shown in this example, when the power per rack exceeds 10 kW, the power distribution loss generated by traditional 12-V DC power is said to reach an intolerable level, but a 48-V DC power supply significantly contributes to power saving for a data center.

What is a -48V power supply system?

Products basically use -48V power supply system, and the actual measured voltage is generally –53.5V. This is because for reliability reasons, communication equipment is equipped with a backup battery (-48V). In order to ensure reliable charging of the battery, the supply voltage needs to be slightly higher than the battery voltage.

Why is a –48 V DC a positive ground system?

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 a 48 volt DC power source?

This technique has gained widespread support toward optimization of components and circuits and achieving industry-wide adoption in the data-center-related businesses. 48-V DC power is applied to the AC/DC power source to the DC/DC power input terminal of each computation board.

Why should you use -48 volt DC?

The use of -48 volt DC also ensures compatibility with safety regulations and guidelines. Standardization plays a crucial role in the seamless operation of complex communication networks.

Can a 48-V DC converter be used with a 12-V DC power supply?

When a 48-V DC power feeding is adopted, the power configuration of the DC/DC converter needs to be changed from the 12-V DC power supply. Briefly described, two methods are used. The single-stage method reduces the 48-V power source to the load voltage by using a single power supply.
