Main electrical and pneumatic technique index for communication power source.


GY-TX system configuration is flexible, all functional modules are standard 2U high, it is very convenient to embed in the system of operators and integrators.
The advanced module design of the embedded communication DC power supply system makes the whole system very small, but it can provide enough power to meet the requirements of the communication system, and meet the characteristics of rack-mounted installation at the same time. The utility model is suitable for wide fluctuation range of power network such as exchange office, computer room, base station, satellite communication, data communication, railway and power system, etc. SETMINI embedded DC power supply system is easy to operate, easy to install and maintain. The system module frame adopts the box-type installation mode, which is convenient to flexibly expand the capacity of the rectifier module and replace the monitoring module.

Ultra-low radiation: the use of advanced electromagnetic compatibility design rectifier module can meet the electromagnetic compatibility limits and measurement methods of communication power equipment the people's Republic of China Communications Industry Standard YD/T983 for conducted and radiated interference requirements;
1.8. The system configuration is flexible, convenient and easy to expand, and various power systems can be configured according to the requirements of customers.
1.9. The products have passed the inspection of the quality Supervision and Inspection Center of the Ministry of Information Industry of the people's Republic of China.

II. Introduction to Modules.
2.1 the rectifier module produced by the company uses pure soft-switching resonance technology, fully supporting hot-swappable. Advanced microprocessors are installed in each module so that the intelligence of the module is greatly improved. The front panel of the module has three LED indicators indicating the Power, communication, and operation status of the module.

III. Functional characteristics.

3.1. Soft switching: the power circuit of the rectifier module is divided into two parts: active PFC correction and DC/DC conversion. The 90V~290V efficiency of wide input voltage range is up to 95%, and the high power density reaches the international advanced level.
3.2.  forced air cooling: advanced circuit design, harsh component material selection, so that the module not only high efficiency, high power density, but also very small heat output, eliminating the heat sink, reducing the volume.
3.3. Hot-swappable: the rectifier module uses non-destructive hot-swappable technology with soft start and current limiting devices for both output and input. When the module is inserted into the system, it will not cause the fluctuation of the output voltage of the system, and the time to replace the module is less than the 1min.
3.4. Protection and Fault Alert: rectifier modules have different response / action modes in different protection / fault types.
3.5. Low-dropout autonomous current sharing: the rectifier module adopts the technology of low-voltage difference autonomous current-sharing between modules. When the monitoring module or individual rectifier module fails, the other modules can maintain the current sharing.
3.6. Stepless current limiting technology: the rectifier module adopts stepless current limiting technology, which is continuously adjustable between 0% and 110% rated current.
3.7. Monitoring performance: the rectifier module has a built-in CPU monitoring and control module, which is responsible for communicating with the monitoring module. The rectifier module sends the on / off current limit point, voltage setting and other parameter setting commands through the RS485 module, and returns the voltage, current, temperature, current limit point on / off status and alarm to the monitoring module in real time.
3.8. fan control and dustproof: the fan adopts stepless temperature control speed regulation, and changes with the output power of the module to minimize noise and prolong the service life of the fan.
