AutomationDirect GS4-4250

The GS4-4250 is a DURApulse GS4 series AC variable frequency drive in an open-frame, wall-mount housing. It takes 460 VAC three-phase input and is rated 250 hp with 3-phase input, using either sensorless vector control (SVC) or V/Hz control to drive three-phase induction motors. It provides RS-485 communications, analog and discrete I/O, and an embedded ladder-logic PLC function.
