Chassis Mount Resistors are an important mechanical component used in industrial applications to protect electrical circuits from overloads and short circuits. They are usually small, round cylinders with knurled grips and a variety of terminal mountings. Their purpose is to dissipate power in a controlled way, reducing the maximum voltage in associated circuits. In general, these components provide either current or voltage limitation in various current applications.

The HS25 2K5 F is a type of Chassis Mount Resistor offered by Allen-Bradley that is designed for medium power applications. With a body diameter of 25mm, it has a low-profile design and is suitable for installing side-by-side with other components. It offers a continuous current rating of 19A and a maximum voltage rating of 2kV. It also has a temperature coefficient of ±100ppm/°C.

The HS25 2K5 F has an axial-lead aluminium terminal system that eliminates contact leakage and improves reliability in high-energy circuits. It also features a specially constructed nickel-coated resistive element that provides superior current rating and low inductance, making it ideal for use in dc-dc converters and high-wave-rectifier circuits. The resistor also comes with creepage and clearance that give it a superior creepage distance compared to other components in the market. This feature allows the resistor to be mounted in close proximity to other components without compromising safety or reliability.

The resistor is designed to operate in a wide range of voltage and temperature ranges. It is suitable for both variable and fixed current applications, and it operates up to 275°C. The device also comes with a variety of voltage ratings and a wide range of current ratings.

The working principle of the HS25 2K5 F is that it dissipates excess energy flowing through the power circuits in a controlled manner. The resistor works by dissipating the energy into heat, which is then absorbed by the resistor’s body and safely discharged to the atmosphere. This prevents dangerous electrical overloads from building up and provides a stable power supply. The resistor also serves to limit current from running through the system in order to avoid damage to other components in the circuit. The resistance of the resistor also allows it to limit the current, and this is adjustable using a potentiometer.

The HS25 2K5 F Chassis Mount Resistor from Allen-Bradley offers superior power handling, excellent temperature coefficient, and low self-inductance. It is designed for a variety of application fields that require reliable current and voltage limitation, including dc-dc converters, high-voltage rectifier circuits, and motor starter circuits. Thanks to its low-profile design and axial-leaded terminals, the component can be installed side-by-side with other components, helping reduce space requirements. Its superior creepage and clearance also make it suitable for close-mounted applications, providing greater safety and reliability.
