summary
With the rapid development of cloud computing, big data, Internet
of things and other new generation information technology, data presents
explosive growth. Communication network is evolving towards 5g network with
higher rate, larger connection and lower delay. However, the problem of large
power consumption of 5g base station also impacts the traditional backup mode. For
the macro station, the large power consumption leads to the increase of the
capacity of the backup equipment, the increase of the number and capacity of
batteries, the limited space of the old base station building, the difficulty
of expansion and transformation; for the new base station building, the cost is
high, and there are few places to use; for the micro station, the diversified
energy input and output are difficult to coordinate and control; the
multi-standard load demand makes the power supply system complicated; the
energy equipment is inefficient, and the energy consumption is serious; the
power consumption is low; The power supply system is difficult to expand and
evolve. Under the impact of these problems, 5g base station power supply with
maintenance free, high reliability, diverse installation methods and high IP
protection level is one of the best solutions to solve the power supply of base
station. Since the 2G era, EVADA has been the supporting power supply provider
of communication equipment. With deep cultivation in the communication
industry, EVADA has accumulated profound industry experience. According to the
use characteristics of the communication industry, EVADA has developed a full
series of base station power products.
