About the 3RA2003
3RA2003 is an HR2000 series controller that is manufactured by Reliance Electric. The stall torque is 54 lb-in. The speed is 3000 rpm. The friction is 0.60 lb-in. The damping is 0.40 lb-in/kpm. The thermal resistance is 0.57°C/watt. The motor weight is 22 lbs. The motor frame is S-4050. Do not operate the controller with amature knowledge of this equipment.
The controller’s maximum A-C line symmetrical fault current is 5000 amps RMS. The current control method is sinusoidal, and the service factor is 1.0. The displacement power factor is 0.96. The maximum load is either 150% for 20 seconds or 200% for 10 seconds. The speed range is 2000:1, the speed loop gain is 6.8 to 35, and the speed offset is 12 RPM. The acceleration and deceleration rates are 0.1 to 1.8 seconds, and the adjustable overspeed trip is 1500 to 3000 RPM. The reference gain is a 0.3 to 2.7 V differential input. The position loop gain is 0.4 to 100 mV/pulse. The test mode reference is 0 to 10 V, and the notch filter is 30 to 1400 Hz. The filter Q factor is 0.5 to 2.5. The inverse time overload is 50 to 100% of the controller’s rated current, and the current limit is 0 to 200% of the controller’s rated current. The D-C Snubber Braking Power is 7.5-15 HP at 220 watts. Lastly, the A-C line voltage variation is 10% of the selected voltage.
