TSC industrial Ethernet switch to achieve redundant power supply - Database & Sql Blog Articles

In industrial automation network environments, the use of redundant power supply is the main technical strategy to eliminate single point of failure in the power system. The so-called redundant power supply means that multiple power supply modules bear the system load at the same time, and once one of the modules has a problem and stops supplying power, the other modules will bear the extra power load on average. In order to improve the fault tolerance of the system and the reliability of long-term continuous operation, each power module in the redundant power supply array is required to have the characteristics of simple design, manufacture, and stability.

TSC industrial Ethernet switches are connected in parallel by dual power modules. When one of the power modules fails, the faulty power supply can be automatically disconnected from the system and a fault alarm is issued. The hot-swap controller is also integrated. Prevents an impact on the load bus of the power supply when the power module is inserted and removed. Overvoltage protection of redundant power supplies When the voltage rises, the charging of the capacitors rises slowly and the voltage rises slowly. This slow charging process allows the power supply output to enter the load evenly in a seamless manner to prevent large inrush currents. Enter the power system.
In the redundant power supply array composed of TSC industrial Ethernet switch power modules, each power module shares the entire load current, and current sharing is achieved between the power modules. The TSC Industrial Ethernet Switch balances the load between the DC output and the DC input of its internal power supply. If one power module fails, another power module load-sharing power input will supply power to the switch, so there will be no service interruption.
TSC Industrial Ethernet switches also increase system reliability. The load balancing power supply will bring the switch to a lower operating temperature and increase the life of the power supply. Overall, component reliability and the average time between failures increase. The TSC redundant power supply also has a strong adaptive capability. It operates from an input voltage of 18VDC to 36VDC and a frequency of 50 to 60Hz. The panel has LED redundant power indicator for the network administrator to know the working status of the switch. The P1 and P2 green lights indicate that the redundant power supply is working properly. Once the power fails, the indicator light will go out.
This redundant power supply design reduces the network failure rate and improves the ease of use and maintainability of the device. With the increasing security and stability requirements of industrial Ethernet, redundant power switches are used in industrial automation network applications. Will be more and more extensive.
