| Application Scope | The THT-20 series intelligent phase-controlled communication power system is widely used in access networks, rural telephone exchanges, small-scale offices, transmission relay stations; microwave, satellite communication stations; and communication equipment for railways and power utilities. | |
| System Features | The THT-20 series intelligent phase-controlled communication power system uses Siemens S7 series programmable controllers as the main control unit and a 5.7-inch LCD touch screen as the human-machine interface. Users only need to monitor and control the system through the touch screen interface. The main circuit adopts a full-bridge controlled rectifier circuit, and the trigger circuit uses programmable integrated circuits. The system can be configured with two groups of batteries running in parallel, or one group running and one group in standby. After setting the parameters, the system can operate automatically without manual intervention, automatically completing battery group charge management. After a power outage and restoration, the system can automatically start and run. The entire device is easy to operate, reliable, fully protected, and highly automated, making it a reliable 48V communication power supply. Input voltage: Two AC380V inputs Output voltage: DC40V～72V (continuously adjustable) Voltage regulation accuracy: ≦±1% Current regulation accuracy: ≦±1% Ripple coefficient: ﹤1% Conversion efficiency: ≧75% (at full load) Insulation resistance: ≧10MΩ Noise: ≦55dB (1 meter from the front and rear doors when closed) | |
