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

Bonitron M3575R Braking Resistors help protect drives from overvoltage faults by dissipating the excess regenerative energy as heat. M3575R Braking Resistors are commonly used in applications where infrequent, low duty cycle, or low horsepower regeneration occurs.

M3575R Braking Resistors 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.

For resistors rated up to the megawatts see the Bonitron M3775R Resistive Load Bank Series. Custom resistors are also available.
