# AutomationDirect GS23-4015

Hardware · `GS23-4015` · verification: source checked

The GS23-4015 is an enclosed general-purpose AC variable frequency drive in the DURApulse GS20 series. It runs from a 460 VAC three-phase supply and is rated 15 hp, driving three-phase induction or permanent magnet AC motors in SVC, V/Hz, FOC or torque control modes. It has an RS-485 port, USB B port, seven discrete inputs, three discrete outputs and integrated dynamic braking, and accepts an optional EtherNet/IP and Modbus TCP card.
