# AutomationDirect GS33-4010

Hardware · `GS33-4010` · verification: source checked

The GS33-4010 is an enclosed DURApulse GS30 series AC variable frequency drive rated for 460 VAC three-phase input and 10 hp. It controls three-phase induction and permanent magnet AC motors using SVC, V/Hz, FOC, encoder or torque control modes. It has an RS-485 port running Modbus RTU or ASCII slave, a USB B port, integrated dynamic braking and built-in Safe Torque Off.
