AutomationDirect GS4-2020

The GS4-2020 is a DURApulse GS4 series AC variable frequency drive in a NEMA 1 enclosure. It runs 3-phase induction motors from a 230 VAC supply, rated 20 hp with 3-phase input and 7-1/2 hp with 1-phase input, using either sensorless vector control (SVC) or V/Hz mode. It has an RS-485 port, integrated dynamic braking, a built-in keypad and screw terminals, with optional EtherNet/IP and Modbus TCP cards.
