# AutomationDirect GS33-42P0

Hardware · `GS33-42P0` · verification: source checked

The GS33-42P0 is a DURApulse GS30 series enclosed AC variable frequency drive rated for 2 hp motors on a 460 VAC three-phase supply. It controls three-phase induction and permanent magnet AC motors using SVC, V/Hz, FOC, encoder or torque control modes, with integrated dynamic braking and a built-in Safe Torque Off function. Setup and monitoring are done through its keypad, RS-485 (Modbus) port or USB B port, and optional communication, encoder and I/O modules can be added.
