Rotary Potentiometers, Rheostats
VS3891K is a power device, which is commonly used in electrical products and components. It is a wide range of application in different fields. VS3891K mainly has two types, they are "potentiometer" and "rheostat".
Application Field
The VS3891K has a wide range of application fields. It can be used for audio control equipment such as public address systems, audio amplifiers, audio mixers, power amplifiers, and sound card. It can also be used for automotive electronics, which can help to control the hydraulic pressure, the engine rotation, the air-conditioning switch and so on. Additionally, in the scientific and industry fields, it can be used in many kinds of electrical equipments like motor speed control, LED strips dimmer, servo control, digital meters and so on.
Working principle
VS3891K can be regarded as a voltage divider, which is composed of two resistors. When the voltage is applied on the two ends of the resistor, the electric current will flow across them. When the rotating knob is turned, the resistance of one or two resistors will change, so the output impedance, current, voltage and other parameters will be changed accordingly. In the case of potentiometers, the third terminal is used to output the voltage of the voltage divider. In rheostat, it’s only used to adjust the impedance of the circuit. By controlling the resistance of the device, the voltage, current, power, and other parameters can be adjusted.
Conclusion
To conclude, VS3891K is a power device which contains two types of devices: potentiometer and rheostat. It has wide range of applications not only in audio equipment, automotive electronics, but also in servo control, LED strips dimmer and other scientific and industrial fields. Its working principle is that it contains two resistors and when one of them changes it will affect the electric current, voltage, impedance and other parameters. Therefore, VS3891K can be used to adjust the characteristics of electrical system.
