Adjustable Power Resistor - D25K20RE

Adjustable power resistors are resistive components that are adjustable to allow for variable control and regulation of electrical current or voltage. The D25K20RE is an adjustable power resistor designed for usage in a wide range of applications such as power supplies, audio and video equipment, industrial controls, industrial instrumentation, robotics, and electrical engineering.

Description

The D25K20RE is an adjustable power resistor with a resistance range of 0.1 to 25K ohms and a power rating of 20 watts. It is composed of three sections: the main resistive body, a base, and a slide adjuster. All of these components are made from tin plated nickel silver and a mixture of epoxy resins for thermal insulation and protection.The resistive body is made from carbon and other conductive elements, and its surface is coated with a black epoxy resin. The resistive body is designed to dissipate heat generated during operation. The base and slide adjuster work to ensure the resistor remains stable while adjusting the in-circuit resistance.

Applications

The D25K20RE is capable of handling a range of applications where current control is desired. Common applications include power supplies, audio and video equipment, industrial controls, industrial instrumentation, robotics, and electrical engineering. It is particularly suitable for large current systems because of its protection from increased current load.

Working Principle

The adjustable power resistor works by changing the in-circuit resistance of the component. This change is accomplished by the base and slide adjuster working in tandem. The base keeps the position of the resistive body steady while the slide adjuster moves laterally. As the slide adjuster moves, the resistance in-circuit changes due to the increase or decrease in the distance of the resistive material which the current must pass through.

Advantages of the D25K20RE

The D25K20RE adjustable power resistor offers several advantages for its users. Its construction from high-quality materials increases the stability and reliability of the component, allowing it to handle a heavy load. The power rating of 20 watts allows for large current systems to be handled and the resistive body does a good job at dissipating the heat generated from the current flowing through the resistor. On top of this, the wide range of applications which the adjustable power resistor can be used in makes it a versatile component.

Conclusion

The D25K20RE adjustable power resistor is an important component in the design and construction of a variety of electrical systems. Its wide range of applications and high power rating make it an ideal choice for large current systems. On top of this, its construction from high-quality materials increases its reliability and stability. Therefore, choosing the D25K20RE adjustable power resistor is an excellent choice for any project requiring its functions.
