Historically, the communications industry equipment has been using -48V DC power supply. -48V is also known as positive ground. Because the smallest communications network and communications engineering are in the telephone network, the telecom bureau power supply voltage are 48V.
Storage batteries are a backup power supply for direct current power which instantaneously begin discharging power when power stops being output by the rectifier in order to provide power in place of the rectifier. What is alternating current power supply?
Communication base station power supply in the tower room power supply system is an essential and important part of the mobile communication network. The current communication power supply voltage level is divided into DC-48V (+24V), AC 220/380V. Communication industry equipment generally use -48V DC power supply, positive grounding, why?
Power supplies for information and communication devices are important devices for providing stable power supply 24 hours a day, 365 days a year for the various communication devices used to provide data communication services, such as telephone and Internet.
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.
Therefore using direct current power from a rectifier connected to storage batteries as input, and inverting it to alternating current allows for continued supply of power to telecommunication equipment even if there is a power outage. Introductions to Shindengen Telecommunication Power Supplies information.
How does a battery charger differ from a simple power supply?
