# AutomationDirect DURApulse GS33-22P0

Hardware · `GS33-22P0` · verification: source checked

The GS33-22P0 is an enclosed DURApulse GS30 series AC variable frequency drive rated 2 hp with a 230 VAC 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 has a B1 frame, RS-485 (RJ45) and USB B ports, spring clamp terminals, integrated dynamic braking and built-in Safe Torque Off.
