Boost far output function:

The output voltage at the central office is not affected by fluctuations in grid voltage, providing a stable high-voltage direct current of 380-1000VDC without generating electromagnetic interference externally. The transmission line core is small and can be laid in the same pipe as small signal transmission lines such as video/audio/control signals

Protection function:

The system includes power line lap protection, human lap protection, short circuit protection, open circuit protection, leakage protection, overvoltage and undervoltage protection, over-temperature protection and lightning surge protection, etc.

Remote control function:

The system is equipped with remote measurement, remote control and remote signaling functions. The upper computer power monitoring platform can remotely and in real time display the real-time input and output data and operation status of each device, ensuring the rapid location of faulty equipment. Moreover, it has a remote start and stop function.

Current carrier communication:

The system adopts power line carrier communication with transmission lines as the carrier signal and closed-loop control, which is both economical and highly reliable. It avoids the instability and incompleteness that may be caused by faults in communication with other communication equipment, thereby ensuring the stability of the system's monitoring, measurement and remote data, and guaranteeing the effectiveness of safety protection measures.

Module Design:

The central office terminal is designed in a modular way, which is convenient for expansion and upgrade. The system adopts an N + 1 redundant design and supports hot plugging

Fault Isolation:

The remote machine has an independent hardware address. In case of any device failure, it will be automatically isolated and will not interfere with each other.

Self-protection function:

The self-protection capability of the equipment: after any abnormal malfunction, the equipment can self-protect itself and automatically recover once the abnormality is removed, reducing a large amount of on-site manual maintenance work.

Self-check function:

The equipment has self-checking capabilities. Faults of each component will be automatically reported, facilitating replacement and maintenance.

National Standard:

This product complies with the national standard "YD/T1817-2008 DC Remote Power Supply System for Communication Equipment".
