1. Modular design, modules can be hot-plugged.
   
   
2. Full front operation, input and output wiring are on the front.
   
   
3. A single module has two outputs: one is -57V/40A output, another is direct output 48V/30A.
   
   
4. The input terminals of the modules are parallel connected, the output terminals are independent, and quick wiring terminals are adopted for output to easily connect..
   
   
5. It is suitable for remote monitoring with 2 alarm dry contacts (input failure, module failure).
   
   
6. It is also equipped with the function of input reverse connection protection, input and output over-voltage protection, input over-current protection.
   
   
7. Boost function can be independently realized with one single module and will not be constrained by power communication.
   
   
8. Module effciency is not less than 96%.
   
   
9. Equipped with RS-485 communication interface.

Photoelectric Complementary Power System is the management system of control used in the supply of power to the communication room using solar energy and city power. It converts power from a solar cell array, city power, or diesel generator set into stable, reliable, low-voltage DC power for communication equipment. Solar energy use to the maximum, input coordination of a variety of power sources, more electric energy stored in the storage bat-tery when the sunshine is enough. While the mains input interface has input and the solar output is insuff- cient, the mains can maintain the load and charge the battery pack. It is the battery pack that discharges to supply power to the load under a stretch of rainy weather with no availability of utility power.

It can be installed in a standard 19-inch cabinet and applied in many fields, for example: 4G RRU remote power supply system, 5GAAU remote power supply system.
