The DURApulse series of AC drives offers all of the features of our GS2 series of drives including dynamic braking, PID, removable keypad and RS-485 Modbus communication.

• The DURApulse AC drive also offers sensorless vector control with the option of encoder feedback for enhanced speed control.
  
  
• The standard smart keypad (aka HIM or Human Interface Module) is designed with defaults for the North American customer and allows you to configure the drive, set the speed, start and stop the drive, and monitor critical parameters for your application.
  
  
• In addition, this keypad has internal memory that allows four complete programs to be stored and transferred to any DURApulse drive.
  
  
• The DURApulse series offers three analog inputs, eleven digital inputs, and one SPDT relay output.
  
  
• Typical applications include conveyors, fans, pumps, compressors, HVAC, material handling, mixing, shop tools, extruding, grinding


DURApulse prices start at $240.00 (GS3-21P0 )

Complete DURApulse Drives Overview

Input and output line reactors are available for DURApulse Drives

• Input line reactors protect the AC drive from transient overvoltage conditions, typically caused by utility capacitor switching. The input line reactor also reduces the harmonics associated with AC drives. Input line reactors are recommended for all installations.
  
  
• Output line reactors protect the motor insulation against AC drive short circuits and IGBT reflective wave damage, and also “smooth” the motor current waveform, allowing the motor to run cooler. They are recommended for operating “non-inverter-duty” motors and when the length of wiring between the AC drive and motor exceeds 75 feet.
  
  
• NOTE: If you purchase an AC line reactor with your AC drive order, you'll receive an an extra year of warranty coverage in addition to the standard warranty period.

Circuit protection devices are essential to prevent costly damage to your AC drive application equipment.

• Fuses and fuse kits are available from AUTOMATIONDIRECT for the GS2 and DURAPULSE AC drives.
  
  
• Replacement fuses are also available.

Braking units are applied to absorb the motor regeneration energy when the three-phase induction motor stops by deceleration.

• Braking Units Are available only for Durpluse Drives.
  
  
• Braking resistors are used to increase the control torque of the AC drive, for frequently repeated ON-OFF cycles of the AC drive, or for decelerating a load with large inertia.
  
  
• GS-2DBU and GS-4DBU, used with GS series braking resistors, provide optimum braking performance.
  
  
Complete Braking Resistors Overview

• Input EMI filters reduce electromagnetic interference or noise on the input side of the AC drive.
  
  
• They are required for CE compliance and recommended for installations prone to or sensitive to electromagnetic interference.
  
  
• RF filters reduce the radio frequency interference or noise on the input or output side of the inverter.
