# AutomationDirect GS33-43P0

Hardware · `GS33-43P0` · verification: source checked

The GS33-43P0 is an enclosed DURApulse GS30 series AC variable frequency drive rated 460 VAC, 3 hp, with three-phase input and three-phase output. It controls three-phase induction and permanent magnet AC motors using SVC, V/Hz, FOC, encoder or torque control modes. It provides RS-485 (RJ45) and USB B ports, integrated dynamic braking, and onboard analog and discrete I/O; optional communication, encoder and I/O modules can be added.
