# AutomationDirect GS23-53P0

Hardware · `GS23-53P0` · verification: source checked

The GS23-53P0 is an enclosed DURApulse GS20 series general-purpose AC variable frequency drive rated 3 hp for 575 VAC three-phase input and output. It controls three-phase induction and permanent magnet AC motors using SVC, V/Hz, FOC or torque control modes, and includes integrated dynamic braking and built-in reverse. Setup and monitoring are done through RS-485 (RJ45) or USB B ports, and an optional EtherNet/IP and Modbus TCP card can be added.
