What Is a Power Controller?
A power controller is a device that can regulate the amount of power or voltage output and is a type of electronic circuit.
There are different types of power controllers, including power controllers that can control voltage and AC power controllers that can control the current of an AC power source.
Uses of Power Controllers
Power controllers that control output voltage are used to prevent abnormal current, heating, and equipment overwork by controlling voltage.
In the case of AC power controllers, they can control the amount of power output from an AC power source and are used to adjust the amount of power to a desired level.
Uses of power controllers include adjusting the brightness of electric lights, and adjusting the airflow of ventilation fans, electric fans, etc.
Due to the nature of the device itself, some power controllers cannot be used, which may cause malfunctions.
Principle of Power Controllers
Power controllers can be used by connecting the device for which current or voltage is to be adjusted between the power supply and the device, instead of connecting it directly to the power supply, and then adjusting it with the knob part of the power controller, etc.
In the case of voltage control, etc., power controllers use the principle of slidacs or series resistors to adjust the voltage, but with this method, it is not possible to adjust the speed of motors and other devices.
In the case of current control such as AC power controllers, the principle of triac control is used to reduce power by switching on and off the triac element to reduce the AC current partially.
