Communication power supply has experienced the first generation, the second generation of linear power supply phase control power supply, the third generation of high-frequency switching power supply, then to the whole digital power supply. Power supply technology has changed from analog to digital to digital leap. At present, the efficient communication power supply, modular UPS, high voltage DC power supply system, power supply technology and products are being more and more popular. The customer put forward higher requirements in efficiency, digital, intelligence and modular of communication power supply.

According to the analysis of China Mobile Design Institute, product efficiency did not get the full attention, the power purchased lives the third generation common power supply during the national power supply purchase. In comparison, the purchasing rate of main European carrier-operator reaches over 80% than domestic in 2011.

In 2013, the overall trend of power supply is the efficient energy-saving. Efficient power can help operators to reduce electricity costs, make the control system more easy to deploy, will become the mainstream. At the same time, the power supply develops to higher density. Saving room area and narrowing the cabinet volume.

Hubei Telecom conduct large scale high efficient energy pilot project reportedly. HUA WEI Network Power won the bid and provided more than 100pcs efficient switch power supply. This is the first time for Hubei to apply the new generation efficient power system and symbolize the an extensive apply of efficient power supply.
