Introduction
It is a power supply of high capacity with two-way AC/DC outputs. The power supply adopts the latest circuit design, which has compact structure and reliable performance. The equipment has high accuracy and high output efficiency. With wide input voltage range, input overvoltage protection,output short-circuit protection, overcurrent protection and overtemperature protection. The cooling uses the natural heat dissipation of the system. 
The entire power supply is strictly designed in accordance with safety regulations and meets the requirements of information technology safety standards. With the following characteristics: Class D lightning protection capability, outdoor with high dust proof and waterproof design, protection level IP65, using contact heat dissipation on the bottom,with metal shell, the power supply housing and cable connector needs to be equipped with anti-off screws, support installation on the pole and wall. Which can be widely applied to the Base Station of GSM/CDMA, Exchange Bureau of medium-low capacity, Satellite Communication, Data Communication,mobile communication,Access network,microwave communication,electric power system,CCTV, traffic lights. ect.
