Chassis Mount Resistors

A Chassis Mount Resistor is an electronic component used to provide resistance to current flow in an electric circuit. The term "Chassis Mount" refers to its mounting method, which allows it to be mounted directly to a chassis, making it easier to access and install in an electrically safe location.

RSN-20-50B Application Field and Working Principle

RSN-20-50B is a Chassis Mount Resistor specifically designed for high-current applications. It is typically used in motor drive applications, providing high-current resistance and power dissipation. The RSN-20-50B is designed to be mounted directly to a standard chassis and is available with a variety of power ratings.

The RSN-20-50B is a Metal Oxide Varistor (MOV) type of resistor. This type of resistor has an electrical characteristic in which the resistance decreases as the voltage increases. This allows the resistor to absorb and dissipate dynamic surges of current, such as those from an inductive or capacitive load.

The MOV\'s ability to absorb and dissipate dynamic surges is what makes it such an ideal choice for motor drive applications. As the motion of the motor\'s drive system changes, so does the load on the transformer. The MOV is able to reduce the voltage to a safe level for the transformer, thus reducing the chances of it being damaged.

The RSN-20-50B has a continuous current rating of 20 amps and a power dissipation rating of 50 watts. This is more than enough power for a majority of motor drive applications, but it should be noted that these ratings may be exceeded under certain circumstances. In order to ensure proper operation, it is essential to select an appropriate size for the job.

In addition to its resistance and power dissipation capabilities, the RSN-20-50B also offers a range of mounting options. It is available with either a threaded inserted mounting or a snap-in mounting option. Each option has its own unique benefits and can be selected depending on the needs of the application.

The RSN-20-50B is a reliable and durable Chassis Mount Resistor, and is an ideal choice for applications requiring a high current solution. Its resistance and power dissipation capabilities make it suitable for a wide range of applications, and its easy mounting options make it simple to install in any environment.
