6 FAQs about [Base station DC remote power supply high frequency flash]
What is the coverage area of 5G high-frequency base stations?
The radius of coverage area of 5G high-frequency base stations will be less than one-tenth of that of 4G base stations, and the coverage area of 5G high-frequency base stations will be less than one percent of that of 4G base stations. The deployment of macro base stations is difficult and the site resources are not easy to obtain.
Can a power supply be remotely sensed?
If there is no dedicated differential amplifier, the power supply can still be remotely sensed. A remote sense resis-tor can connect the load voltage back to the converter, compare the load voltage to the reference voltage, and regulate the output voltage.
What does a 42 volt power supply mean?
42V. It means that if the voltage drop is more than 6V, the ICT equipment will be protected. It can be seen that when the length more than 120m in the 4G system and the length more than 70m in the 5G system, the ICT equipment will be off because the low voltage protection of the power supply system.
What is a Telecom DC power system?
The telecom DC power system typically includes the national electricity grid system, a diesel generator, a self-acting AC automatic transfer switch (ATS), a power distribution system, solar panels or boards, controllers and chargers, rectifiers, backup batteries arranged in series, and the corresponding cables and breakers. Figure 1.
Why does a remote sense line oscillate when a dynamic load is applied?
However, when a dynamic load is applied as illustrated in Figure 2, the remote sense line picks up the dynamic voltage and tries to compensate for the voltage drop across the parasitic resistance (RP). This may result in a low-frequency oscillation due to the controller propagation delay.
