General Purpose AC Variable Frequency Drives (VFD)
General purpose variable frequency drives (VFD) enable speed control for three-phase AC motors such as those in conveyors, fans, pumps and material handling. Available in capacities up to 30hp, various models offer V/Hz, sensorless vector or field oriented vector control modes. A full line of accessories ensures a reliable installation.

DURApulse GS20
AC Drives
DURApulse GS20 AC drives offer several different speed control modes: standard V/Hz with pulse input feedback, sensorless vector (SVC) for Induction Motors (IM) and Permanent Motors (PM), and ultra precise Field Oriented Vector control (FOC) for maximum open loop speed regulation control.
DURApulse GS20 offers two analog inputs, one analog output, one frequency output, seven digital inputs (including one pulse train input up to 33kHz), two digital outputs, one SPDT relay output, and two STO inputs. All of the analog and digital I/O can be configured for a wide variety of input or output functions. One option card slot is available for either the backup control power option card or Ethernet/IP and Modbus TCP communication option card.
The DURApulse GS20 new generation high performance vector control drives provide many standard and advanced functions - all in a compact unit that has been reduced 40% in size. A NEMA 4X version provides service in the harshest of environments.
The drives include many of the same standard features as our GS family of drives including dynamic braking, PID, removable keypad, and RS-485 Modbus communication.
The GS20 drive expands the DURApulse family by adding single-phase input capability (all 230VAC drives can be supplied single-phase), a built-in PLC, and optional EtherNet/IP and ModbusTCP communication card. The drive supports up to four (4) independent IM motor parameter sets or supports control of a single AC PM motor.

Testimonial for
GS21-22P0
These are the most easy to use VFD that I have seen on the market. The two line display provides good information without having to refer to a manual. The durability have improved substantially from about 12-15 years ago when these drives did not last too long. Now I only by GS3 drives.
