Embedded power supply is a box type power supply system, which is embedded in the integrated communication cabinet to provide basic DC power for communication and data equipment in the same cabinet. It also has certain versatility. Generally speaking, the input of embedded power supply is AC 220 V, and the output is dc-48v or + 20V power supply equipment.
Most of the embedded power supply is used for other communication products. Therefore, its applications are miniaturized and integrated communication products, such as access products, data products, switching end office, small switch, small mobile base station, etc. In addition, in some cases, the embedded power supply can also be used as a small power system.
The main features of the popular embedded power supply of Qunfang technology company are as follows:
*The voltage range is 85V AC ~ 300V AC
*Perfect battery management function
*The network design provides one COM interface and one RS485 / RS232 interface
*It supports Huawei network management protocol and general electric protocol, and can communicate with Huawei neteco network management, M2000 network management or third-party network management. The network is flexible and can realize remote management and unattended
*Support LCD interface display and key operation
*Support rectifier module hot swap
*Support high efficiency and standard efficiency rectifier module mixed plug with the same capacity
*The power factor of rectifier module is 0.99
Working principle of embedded power supply popular in Qunfang technology company
The working principle of the power supply system is that the alternating current enters the rectifier module through the AC input port
The AC is converted into – 48V DC, and the DC output port supplies power to the load.
When the AC supply is normal, the rectifier module not only supplies power to the DC load, but also provides charging current for the battery. When hand in
When the current is cut off, the rectifier module stops working and the battery supplies power to the DC load. After the AC power is restored, the rectifier module will give the
DC load power supply, and charge the battery to supplement the power consumption.
The monitoring unit monitors the operation status of each component of the power supply system in real time, and carries out corresponding intelligent control. In case of any abnormality, it shall report the alarm signal in time.
