Chassis mount resistors are an integral part of electronics used to control current flow in electrical circuits. The UAL25-500RF8 is a high-power adjustable wirewound chassis mount resistor that can operate at multiple frequencies and generate enough heat to be used in various applications. It has a maximum operating power of 500 watts and is designed for use in electronic equipment, as well as watt-hour power metering, recording, measuring, testing, operation and alignment of semi-conductor development equipment, and in other instrumentation equipment. This chassis mount resistor allows the user to easily adjust the power level to fit their specific needs, providing a wide range of applications and functions.

The UAL25-500RF8 is a non-inductive, non-capacitive, adjustable power resistor that can be fine-tuned to cater to a wide range of applications. This chassis mount resistor is considered a "variable impedance" component which means that its resistance is adjustable, allowing it to be used as a potentiometer, a voltage divider, or any other type of adjustable power resistor. The resistor is an adjustable wirewound type that is comprised of two sections: the core, which is made up of adjustable wirewound, and the support frame, which supports the core and holds it firmly in place.

In order to use the UAL25-500RF8, it must be connected between the circuit and the power supply. This connection will ensure that all of the wattage is dissipated through the resistor, and not through the applied load. When the power is off, the resistor will remain off for a short period of time before it automatically goes back on again to provide an adjustable amount of power to the application.

The working principle of the UAL25-500RF8 is simple. The resistor is constructed so that when power is applied, the resistance of the element increases in proportion to the applied voltage. This increase in resistance results in the generation of heat, which is dissipated through the resistor. As a result, the power delivered to the application is proportional to the resistance of the element.

The UAL25-500RF8 comes with dual voltage ranges to accommodate different power needs. It features a high power rating and an adjustable heat dissipation, allowing it to be ideal for applications that need precise power tolerances for various applications, such as recording equipment, power metering, and instrumentation systems. The resistor can be adjusted on-site and can be used in many different applications, making it an ideal chassis mount resistor for many applications.

Overall, the UAL25-500RF8 is an adjustable, non-inductive, wirewound chassis mount resistor that is ideal for applications that require precise power tolerances and adjustable heat dissipation. It operates at multiple frequencies and has a maximum operating power of 500 watts, making it perfect for watt-hour power metering, recording, measuring, testing, operation, and alignment of semi-conductor development equipment. This resistor is designed for use in electronic equipment and can be adjusted on-site, making it an ideal chassis mount resistor for many applications.
