Original Press Release:

DURApulse GS20 Series High Performance AC Drives from AutomationDirect

The DURApulse GS20 Series of next generation high-performance vfd drives provides many standard and advanced functions in a compact reduced size unit. The new GS20X series of AC drives is IP66/NEMA 4X rated for operation in harsh 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. An available GS2 mode duplicates exact parameter configuration of GS2 series mini AC drives.

GS20 drives are available from 1/4 to 30 hp in single-phase 120VAC input, single-phase/three-phase 230VAC input, and three-phase 460VAC and 575VAC input. GS20X NEMA 4X drives are available up to 10hp.

Several speed control modes are available including standard V/Hz control with pulse input feedback, sensorless vector control (SVC) for induction motors (IM) and permanent Motors (PM), and precise Field Oriented Vector control (FOC) for maximum open loop speed regulation control.

AutomationDirect DURApulse GS20(X) drives start at $135.00 and have a two-year warranty.
