Detailed content
-
- Redundant Switching Time: ≤5ms, realizing seamless switching of power supply.
- Functional Characteristics:
- The redundant design of dual power supplies ensures that the system will not be powered off due to the failure of a single power supply channel, and improves the availability of the system.
- It has a high – efficiency power conversion circuit, which can reduce energy loss and heat generation during the power conversion process.
- The output voltage is stable, and the voltage fluctuation is small even when the load changes, which can ensure the stable operation of the system modules.
- The front – panel indicator lights can display the working status of each power supply channel and fault information, which is convenient for on – site personnel to monitor and maintain.
- It supports hot – swapping, and the faulty power supply module can be replaced without stopping the system operation, ensuring the continuity of the production process.
- Application Scenarios: It is mainly used in the power supply of the control cabinet modules in the petroleum and chemical industry’s distributed control systems; the power supply of the safety instrumented systems in the coal chemical industry; the power supply of the control system modules in the nuclear power plant auxiliary systems; and the power supply of the automation equipment in the semiconductor manufacturing industry, which has high requirements for power supply reliability.
