Communication power supply Oct 18, 2021


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, EVADAhas 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.
