| Overview | The THT-10 series high-frequency communication power supply tracks the latest developments in international communication power supply technology, adopting advanced power control technologies and components. With its advanced modular design and automatic current sharing technology, the system's capacity can be easily expanded with N+1 redundancy. It has excellent electromagnetic compatibility. Fully intelligent design, equipped with a centralized monitoring unit, supports three remote functions (remote measurement, remote signaling, and remote control) to achieve computer management. By communicating with a remote monitoring center, it enables unattended operation, meeting the requirements of modern communication technology development. Widely used in access networks, rural communication stations, small and medium-sized offices, transmission relay stations, microwave and satellite communication stations, and communication equipment for railways and power systems. | |

| Applicable Scope | The THT-20 series intelligent phase-controlled communication power supply system is widely used in access networks, rural communication stations, small and medium-sized offices, 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 supply adopts Siemens S7 series programmable controllers as the main control unit and 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 uses programmable integrated circuits. The system can configure two sets of batteries to run in parallel or one set to run while the other is on standby. Once parameters are set, the system can operate automatically without manual intervention, automatically managing the charging of battery groups. When AC power is cut off and restored, the system can automatically restart. 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% (full load) Insulation resistance: ≧10MΩ Noise: ≦55dB (1 meter away from the front and rear doors when closed) | |
