System structure and the standard

System Feature

1. With advanced design the module of SETMINI embedded DC power system is small, but it can provide enough power to meet the communication requirements of the system, consistent with the characteristics of rack installation.

2. The system is suitable for all sizes of exchange room, base stations, satellite communications, data communications, railways and power systems, etc. Occasions of power grid fluctuations in a wide range.

3. Easy to operate, install and maintain. System module plug box with insert box installation for flexible expansion and replacement of monitoring module.

Features:

1. With active power factor compensation technology power factor of rectifier is up to 0.99

2. Standard height 2U, the weight of each module is 2.4kg, output current is 33A, high power density.

Rectifier modules adopted soft switch technology, while load rate is 10％ then efficiency can be 91％, 50％ load rate the efficiency can be above 95％

3. Complete battery protection and low load cut management; 2-grade low voltage off load, allowing users to implement in emergency situations away from the normal load, and then off the main load, which maximally protect load and battery.

4. Hot swap with no damage technology is adopted in rectifier and monitor. Plug and play;

5. Standard RS232 communication interface; 3 alarm dry contact alarm: Emergency alarm, main alarm, general alarm

6. Complete fault protection, alarm function;

7. Low radicalization: Advanced EMC design to meet the communication power rectifier equipment electromagnetic compatibility limits and measurement methods in the PRC telecommunications industry and standard YD/T983 conducted and radiated interference requirements.

8. System configuration is flexible and convenient, easy to expand; can be configured according to customer demand;

9. Products have passed the inspection of the Ministry of Information Industry Quality Supervision and Inspection Center.
