The controller of the automatic switch plays a vital role in the power system. Its main functions can be summarized as follows
First, automatic switching power supply
Real-time monitoring: The controller can monitor the status of the main power supply and standby power supply in real time, including voltage, current and other parameters.
Intelligent judgment: When the main power supply fails (such as abnormal voltage or power failure), the controller can quickly make intelligent judgment to determine whether the power supply needs to be switched.
Automatic switching: Once it is determined that the power supply needs to be switched, the controller will automatically issue instructions to drive the actuator to switch the load circuit from the main power supply to the standby power supply to ensure the continuity and reliability of the power supply.
Second, protection function
Electrical protection: The controller has the function of short circuit and overload protection, which can cut off the power supply in time when the circuit is short circuit or overload, and prevent the occurrence of safety accidents such as equipment damage or fire.
Voltage protection: At the same time, it also has overvoltage, undervoltage protection function, when the power supply voltage exceeds the set range, can automatically take protective measures to protect the equipment from the impact of voltage fluctuations.
Lack of phase protection: In the three-phase power supply system, the controller can also detect the lack of phase and take corresponding protective measures when the lack of phase.
Third, intelligent control and management
Parameter setting: Users can set switching parameters on the controller according to actual needs, such as voltage range, switching time, etc., to meet the needs of different occasions.
Status display: The controller is usually equipped with a display or indicator to display power status and fault information in real time, which is convenient for users to monitor and manage.
Remote monitoring: Some advanced controllers also support remote monitoring function, users can remotely view the device status through the network, receive fault alarms, etc., to achieve remote management and control.
Fourth, improve the reliability of power supply
Automatic detection and switching: The controller can automatically detect power failure and switch without manual intervention, which greatly improves the reliability and stability of the power supply.
Reduced downtime: Quickly switching to backup power in the event of a power failure reduces equipment downtime due to power outages and reduces production losses.
5. Energy conservation and environmental protection
Reduce energy waste: By precisely controlling the switching and protection functions of the power supply, energy waste due to power failure is reduced.
Meet the environmental requirements: At the same time, the controller design also meets the environmental requirements, reducing the pollution and damage to the environment.
