Bonitron M3575R Standard Duty UL Braking Resistor

M3575R - Standard Duty UL Braking Resistor

Product Resources

- 1 to 33hp : 6 to 20% Duty -

Bonitron M3575R Resistive Braking Modules provide drive protection from overvoltage faults due to regenerated voltage by dissipating the excess energy as heat. M3575R Resistive Braking Modules are typically used in applications where infrequent, low duty cycle, or low horsepower regeneration occurs. The standard duty cycle for the Dynamic Braking Modules is 20% or less.

The M3575R Modules are easily applied as resistive loads for use with a drive’s internal or external braking transistor. Sizes up to 33 horsepower in a single unit are available and may be paralleled for higher requirements. Units have been designed and tested to ensure that cabinet temperatures are less than 85º C. Over-temperature contacts are standard on all Bonitron resistors.

For resistors rated up to 3MW see the Bonitron M3775RK Resistive Load Bank. Custom resistors are also available..
