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 48 a good system voltage?Back in the day, when Telephony equipment was being developed, 48 was the chosen system voltage because it’s considered safe “low voltage”, and reduced amperage requirement of equipment powered at this voltage.
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.
Does a telecommunications network need a battery backup system?Telecommunication networks often require uninterrupted power supply to maintain critical operations during power outages. -48 volt DC power is well-suited for integrating battery backup systems. Many telecommunications installations include batteries capable of providing backup power to ensure continuous operation during emergencies.
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 activiti
