Rotary Potentiometers and Rheostatsare electrical components used to control the electric current in a circuit. The difference between the two is that a potentiometer can be infinitely adjusted, while a rheostat has only two settings, on and off. The 91A2A-B28-D20/D20L is a rotary potentiometer specifically designed for adjustable power supply systems. It comes with an adjustable resistance knob built into the body of the potentiometer.

Application Field

D20/D20L potentiometers are used in a variety of applications, such as voltage regulation, amplifier circuits, substation/transmission line protection, and other adjustable power supply applications. The D20/D20L can be used in any application requiring a continuously variable resistance. It can also be used for trimming, which is the process of fine-tuning a circuit for optimal performance.

Working Principle

Like all potentiometers, the 91A2A-B28-D20/D20L Potentiometer works by using an internal resistor to regulate the current through the circuit. The resistance is determined by the position of the adjustment knob, which can range from 0-100. The current is adjusted by rotating the knob, which changes the amount of resistance in the potentiometer. When the knob is rotated clockwise, the resistance value of the potentiometer increases, while rotation counter-clockwise will decrease resistance. This changing resistance is used to control the current in the circuit.

In addition to being adjustable, the 91A2A-B28-D20/D20L also features current limiting protection. This feature is designed to prevent the user from over-adjusting the potentiometer, potentially causing damage to the circuit. The current limiting protection can be adjusted using an external resistor, or by changing the internal resistance of the potentiometer. By controlling the current, the 91A2A-B28-D20/D20L is able to provide a safe and adjustable power supply.

Conclusion

The 91A2A-B28-D20/D20L Rotary Potentiometer is a versatile component that can be used in a variety of applications. It is well suited for adjustable power supply systems, as it allows for precise voltage regulation and current limiting protection. Moreover, its adjustable knob allows for easy trimming, allowing the circuit to be fine-tuned for optimal performance. The 91A2A-B28-D20/D20L is an excellent choice for any application requiring an adjustable rotary potentiometer.
