# AutomationDirect GS33-40P5

Hardware · `GS33-40P5` · verification: source checked

The GS33-40P5 is a DURApulse GS30 series enclosed AC variable frequency drive rated 1/2 hp on a 460 VAC three-phase input. It controls three-phase induction and permanent magnet AC motors using SVC, V/Hz, FOC, encoder or torque control modes. It provides an RS-485 and USB B port, analog and discrete I/O, integrated dynamic braking and optional communication, encoder and I/O modules.
