Chassis Mount Resistors are used in many electronic devices such as computers, radios, televisions, radios and home audio systems. They are usually attached to the chassis of a device and provide protection against short circuiting. The RER75FR221MCSL is a type of chassis mount resistor that is designed to protect various high powered electronic applications.The RER75FR221MCSL application field is mainly hoisting and material handling systems, transportation, and industrial process control systems. They can also be used in applications requiring protective or short-circuit devices, such as switchgear, bus bars, and cable trays. The RER75FR221MCSL has an operating temperature of -55°C to +125°C, features a tolerance of ±2% and a resistance of 100Ω to 10KΩ.The RER75FR221MCSL also has high-voltage capability and is designed to provide over-current protection. It is capable of withstanding surge currents up to 1000A and over-current conditions up to 500A. Its operating voltage is from 250V to 600V DC and its power rating is up to 5KW at 230V AC. Additionally, the RER75FR221MCSL features a flame-retardant sleeve design and nickel-plated terminals for added protection.The working principle of the RER75FR221MCSL is relatively simple. It consists of a resistor element that is connected in series with the load. When the current flowing through the load increases beyond a certain point, the resistor element absorbs the excess current and limits it so that it does not exceed the predetermined maximum current. This prevents the load from being damaged due to excessive current. Moreover, the resistor element also acts as a shock absorber that protects the device from overvoltage and power surges.In conclusion, the RER75FR221MCSL is a type of chassis mount resistor that is designed for applications that require protection from over-current and overvoltage. It provides reliable protection and an excellent range of applications. Furthermore, its working principle is relatively simple and involves a resistor element connected in series with the load to limit the current and protect the device from overvoltage and power surges.
