Adjustable power resistors control the flow of electric current in electrical circuits and systems. They are used in various applications including automotive electronics, power converters, phase control systems, and medical and telecommunications equipment. The D12K800 is a well-known adjustable power resistor that offers a wide range of current ratings and power levels. This article explores the application fields and working principle of the D12K800 adjustable power resistor.

Overview of D12K800

The D12K800 is a current-controlled adjustable power resistor developed by Diasemi Technology. It is a general purpose, non-inductive adjustable resistor that is capable of handling up to 800mA of continuous current at temperatures up to 250°C. The D12K800 has a robust construction and is designed for applications that require high performance, reliability, and a long operational life.

The D12K800 adjustable power resistor features a single-slot design, which reduces the size and number of components required for installation. This design also helps minimize power dissipation and heat generation, which improves device performance and reliability. The resistor can be easily adjusted to the required level of power or current within the specified operating limits using a screw-mounted potentiometer.

Applications of D12K800

The D12K800 adjustable power resistor has several applications. It is often used in automotive electronics to regulate the current flow in motors and actuators. It is also used in power converters and phase-control systems. These systems require adjustable resistors to control the current in the circuits, and the D12K800 can handle these tasks with ease. In addition, the device can be used in medical and telecommunications equipment to regulate power supply and current levels.

The D12K800 adjustable power resistor is also useful in LED lighting applications. LED lights usually require a specific current level to operate, and the D12K800 can be used to adjust the current flow. This allows users to maximize the performance of their LED lights while reducing power consumption. The adjustable resistor can also be used in audio and video applications to regulate the power output from an amplifier.

Working Principle

The primary function of the D12K800 adjustable power resistor is to regulate the current flow in electrical circuits. It works by placing a variable resistor in the circuit, which is controlled by the user. The resistor consists of two terminals, a positive and a negative, and a potentiometer that adjusts the resistance. The potentiometer is connected to a mechanical screw that, when twisted in either direction, increases or decreases the resistance.

When the voltage in the circuit exceeds a certain limit, the current flow is restricted by the adjustable resistor. The adjustable resistor is set to the desired level, and the current flow is adjusted accordingly. The D12K800 can handle up to 800mA of continuous current, and it has a maximum operating temperature of 250°C. This allows it to be used in high-power applications.

Conclusion

The D12K800 adjustable power resistor is an invaluable component in many different applications. It is an effective device for regulating the current flow in circuits and its robust construction and long operational life make it suitable for a wide variety of applications. The D12K800 is suitable for automotive electronics, power converters, phase control systems, medical and telecommunications equipment, LED lighting, and audio and video applications. It is also easy to adjust, making it an ideal choice for those who need to adjust the power flow quickly and reliably.
