1U Telecom Rectifiers

This switch mode DC power supply system developed by our company is a high effective, high intelligent telecommunication power supply system consisting of -48V/20A high frequency switch mode rectifier modules developed by our company, The switch mode DC power supply system can suitable for the various systems of telecommunication, Such as program-controlled switchboard, mobile phone system, fiber-optic system, digital microware system, railway telecommunication station, and call-transmission communication station.

The system is of modular design with international standards. The modules are easily accessible from the front. As N+1 configuration is adopted, it is very convenient for users to change or enlarge the configuration. The system also can be installed beside communication equipment because of its excellent electricity and magnet compatibility and strict safety requirements. With perfect centralized monitor and remote control and intelligent management function, the system can perform remote monitor and control for various communication power supplies without human attendance.

YK-48/20 is a microprocessor programmer switch mode single-phase input rectifier module to provide the 48V/20A DC power for communication. The interior circuit of rectifier module is adopted the full-wave bridge rectifier and pulse width modulation technology and power factor compensation technology. It's working frequency is 100KHz. It has multifunction display and adjustment. With the application of the programmer monitoring dot matrix LCD, the working contents and operating status of rectifier module can be displayed completely and clearly.
