THT-20 series intelligent phase controlled communication power supply
Scope of application
THT-20 series intelligent phased communication power supply system is widely used in access network, farm work, medium and small scale Bureau, transmission relay station, microwave, satellite communication station, railway and power communication special equipment.
System characteristics
The THT-20 series intelligent phased communication power supply adopts SIEMENS S7 series programmable controller as the main control unit. The 5.7 inch LCD touch screen is used as the human-machine interface. Users can monitor and control the system only through touch screen interface. The main circuit uses a full bridge controlled rectifier circuit, and the trigger circuit uses programmable integrated circuit.
The system can be configured with two sets of batteries, parallel operation, one set of running and one set of spare. When the parameters are set, the system can run automatically without manual operation and automatically completes the charge management of the battery pack. The system can operate automatically after the power supply is stopped and the power is reconnected. The complete set of equipment is convenient to operate, reliable in work, complete in protection and high in automation. It can be used as a reliable power supply for 48V communication.
Input voltage: two AC380V
Output voltage: DC40V ~ 72V (continuous set)
Voltage accuracy: less than 1%
Current accuracy: less than 1%
Ripple coefficient: < 1%
Conversion efficiency: 75% (full)
Insulation resistance: 1010M ohm
Noise: less than 55dB (before and after the closure of the door 1 meters)
