| Applicable Range | The THT-20 series intelligent phase-controlled communication power system is widely used in access networks, rural telephone networks, small- and medium-scale exchanges, transmission relay stations, microwave and satellite communication stations, and communication equipment for railways and power systems. | |
| System Features | The THT-20 series intelligent phase-controlled communication power system adopts Siemens S7 series programmable controllers as the main control unit, with a 5.7-inch LCD touch screen as the human-machine interface. Users can monitor and control the system through the touch screen interface. The main circuit uses a full-bridge controlled rectifier circuit, and the trigger circuit adopts programmable integrated circuits. The system can be configured with two sets of batteries that operate in parallel or with one set running and the other as backup. Once parameters are set, the system can operate automatically, completing battery charging management without manual intervention. After an AC power outage and restoration, the system can automatically restart. The entire device is convenient 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 Precision: ≦±1% Current Regulation Precision: ≦±1% Ripple Coefficient: ＜1% Conversion Efficiency: ≧75% (at full load) Insulation Resistance: ≧10MΩ Noise: ≦55dB (1 meter away from the front and rear doors when closed) | |
