Boost power supply system-refers to a new boost power product with a conversion function of DC48Vto DC57V. The input end of the product is taken from the output end of the DC power distribution unit of the communication base station power system, and DC is realized after the internal DC/DC conversion circuit of the product. The output port boost func- tion supports the long-distance deployment of 5GAAU equipment. A single boost power distribution unit can realize the remote deployment of 1 user’s 5G main equipment to provide power to AAU.
 
Product Features
• Modular design, modules can be hot-plugged;
• Full front operation, input and output wiring are on the front;
• A single module has two outputs, one is -57V/40A output, and the other is direct output 48V/30A;
• The input terminals of the modules are connected in parallel, the output terminals are independent, and the output adopts quick wiring terminals for easy connection;
• With 2 alarm dry contacts (input failure, module failure), it is convenient for remote monitoring;
• Input reverse connection protection, input and output over-voltage protection, input over-current protection and other functions;
• A single module can independently realize the boost function without relying on power communication;
• Module effciency is not less than 96%;
• Equipped with RS-485 communication interface.

Application Scenarios
It is suitable for installation in a standard 19-inch cabinet and used in applications such as 4G RRU remote power supply system and 5GAAU remote power supply system.
