Product Features:
1. The power supply screen adopts a main and backup power supply control circuit for the two AC power inputs. When the main power supply voltage is unstable or fluctuates greatly, it can be manually switched to the backup power supply for power supply 2. Two input power supplies are converted through a conversion circuit to supply power to the high-frequency switching power supply module. The high-frequency switching power supply modules are AC/DC converted into the power required for communication and signal equipment 3. The switch power supply adopts standardized module design and plug-in replacement technology. Various power modules can work in an "N+1" redundant hot standby mode and output in separate circuits 4. Adopting the AMZ series high-frequency DC module specially developed for railways, the output is uninterrupted during the conversion of two input power sources 5. The power supply screen adopts intelligent monitoring and is also equipped with sound and light alarms 6. The monitoring unit of the system achieves remote monitoring and centralized management through RS485 communication interface 7. The monitoring unit of the system is equipped with a backup power supply battery pack. When both input power sources are interrupted, the monitoring unit can still query and display 8. Improve electromagnetic compatibility, lightning protection measures, and ensure high stability and reliability of the system in harsh environments.
