HJ057 Series High-Performance Power Systems

Improve the power supply system, boost the new product power with conversion function of DC48V to DC57V. The input of the product is derived from the output side of the DC distribution unit at the communication base station power system side, and DC is realized by the internal DC/DC conversion circuit of the product. The output port boost func- tion can support 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 for power supply to AAU.

1. Modular design, modules hot-pluggable.
   
   
2. Front accessibility, all input and output wiring from front.
   
   
3. One module provides two independent outputs: one is insulated -57V /40A output, the other is direct output 48V/30A.
   
   
4. Input terminals of modules are paralleled internally, output terminals are independent, and the output uses quick wiring terminals for easy connection..
   
   
5. With 2 alarm dry contacts, remote monitoring is convenient.
   
   
6. Input reverse connection protection, input over-voltage and output over-voltage protection, input over-current protection, etc.
   
   
7. Supporting boost function of independent module operation without relying on power communication.
   
   
8. The module efficiency is not less than 96%.
   
   
9. Equipped with RS-485 communication interface.

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.
