Trimmer Potentiometers: 72PR100KLFTB application field and working principle

One of the more common tools used in the electrical industry is the 72PR100KLFTB trimmer potentiometer. Potentiometers are used to measure electrical potential – or voltage – across a number of different circuit configurations.

In a nutshell, the 72PR100KLFTB is an adjustable resistor – or variable resistance – whose value is adjusted manually to increase or decrease the electrical potential across a circuit. It is used in many different applications, from adjusting amplifier levels to diverse industrial uses.

Applications

Potentiometers are used in a broad array of applications, including marine and safety applications. In these applications, the potentiometers are used to control the voltage within a circuit. For example, one might use the 72PR100KLFTB trimmer potentiometer to adjust the speed of a ceiling fan, or in a larger context, to regulate engine speed.

The 72PR100KLFTB is also commonly used to adjust the level of a given electronic component, such as an amplifier. This procedure is referred to as “leveling”. Since amplifiers are so vital in modern electronic devices, they must be properly adjusted to ensure their efficient operation.

In addition, potentiometers are used in industrial contexts to adjust parameters of a device, such as electric motor speed. This can be achieved by regulating the voltage across the motor, which in turn will control its speed.

Working principle

At their core, trimmer potentiometers are made up of three electrical connections: power (V+), ground (V-), and the signal terminal (SW). These three connections must be properly connected in order for the device to perform correctly.

When the 72PR100KLFTB is in operation, the wiper – which is the mechanical part of the potentiometer – applies a linear proportion of the power source potential to the signal terminal. The degree to which this is facilitated depends on the position of the adjuster, and can be fine-tuned to different degrees of precision of up to 100,000 increments.

The 72PR100KLFTB also features a wide temperature range of -55°C to +125°C, so it is suitable for a variety of different applications. Overall, it is designed to endure extreme stress, and thus it boasts an incredibly long lifespan.

Conclusion

The 72PR100KLFTB trimmer potentiometer is a versatile tool used in a wide range of applications. From adjusting amplifier levels to controlling motor speed, this device is extremely useful in both industrial and safety settings. Its ability to perform under extreme conditions, and its high degree of accuracy, make it an invaluable asset in any electrical project.
