- 10 to 100% Duty -

Bonitron M3775RK Braking Resistors offer resistive load banks to cover most braking applications with variable frequency drives. The M3775RK Braking Resistors are available from 1 – 3000 Hp and can handle from a 10% up to 100% duty cycle. M3775RK Resistive Solutions are available based on application requirements. Bonitron offers a wide range of technologies for all your resistive load applications.

Smoothwound
Smoothwound resistors are most commonly used for light-duty braking of variable frequency drives, small horsepower motor control, space heaters and any low wattage, high resistance load application and can be used in AC or DC power circuits. They are suitable for continuous duty applications where high resistance and low current are required. These units are designed to withstand considerable shock, making them suitable for some high vibration applications.

Ribbonwound
Ribbonwound resistors are similar to Smoothwound resistors in most respects and are also most commonly used for motor acceleration and braking, but are also suitable for light-duty braking of variable frequency drives, small horsepower motor control, space heaters. The ribbed edges enhance heat dissipation and permit higher wattage ratings for lower ohmic values and can be used for AC or DC power applications. These units are designed to withstand considerable shock, making them suitable for some high vibration applications.

Wirewound T
Wirewound resistors are designed for low current applications and are suitable for continuous duty applications where high resistance and low current are required, including motor control, dynamic braking, neutral grounding and load testing. They can be used for AC or DC power applications. The wirewound resistor will withstand considerable shock and vibration, qualifying it for use in most harsh environments.

Edgewound
Edgewound resistors are most commonly used for VFD braking, motor control, load banks, neutral grounding applications and can be used for AC or DC power applications. They are suitable for continuous duty applications where low resistance and high current capacity are required. The high element mass allows them to withstand high current, intermittent duty applications. This characteristic, combined with high-temperature ceramic insulation, makes the edgewound ideal for neutral grounding applications, which reach temperatures as high as 800°C.

Grid
Grid resistors are most commonly used for motor acceleration and braking, but are also suitable for load banks, harmonic filtering and some neutral grounding applications and can be used for AC or DC power applications. The rigid construction of the elements make them well suited for use in almost any environment, including high vibration areas such as overhead cranes operated in steel mills and manufacturing plants.
