。Can match with our dynamic compensation controller.
A switched capacitor contactor is a device used in electrical systems to switch between two capacitors.
Capacitors are electronic components that store electrical energy and release it when needed. They are commonly used in various applications such as power factor correction, motor starting and filtering.
In some cases, multiple capacitors are used in the system to meet specific requirements. For example, in power factor correction, multiple capacitors can be connected in parallel to compensate for reactive power in the electrical system.
Switched capacitor contactors allow automatic switching between different capacitors according to system requirements. It usually consists of a mechanical switching mechanism (such as a relay or contactor) and a control circuit that monitors the power factor or other parameters of the system.
A switched capacitor contactor can be programmed to switch capacitors based on a predefined set of conditions. For example, it can switch to higher or lower capacitance capacitors depending on the power factor or voltage level of the system.
By using switched capacitor contactors, a system can optimize its power factor correction or other capacitor-related functions, ensuring efficient and reliable operation.
