About the 3RR2001
3RR2001 is a DC Snubber Resistor manufactured by Reliance Electric as part of their HR2000 series. While the controller is in regeneration mode, DC Snubber Resistors increase the controller’s duty cycle, which is the percentage of total time that the controller is decelerating. To select the proper number of resistors, determine either the continuous braking power or the duty cycle on intermittent braking applications. 3RR2001 requires 4 resistors and fits a controller horsepower of 1-2 HP. Under continuous duty, the power dissipation for this part is 105 watts. Under intermittent duty, the instant power dissipation is 3183 watts and the maximum duty cycle percent of time is 7%.
