# AutomationDirect GS33-2030

Hardware · `GS33-2030` · verification: source checked

The AutomationDirect GS33-2030 is an enclosed DURApulse GS30 series AC variable frequency drive. It accepts 230 VAC three-phase input, is rated 30 hp, and controls three-phase induction or permanent magnet AC motors using SVC, V/Hz, FOC, encoder, or torque mode. It provides RS-485 Modbus communication, integrated dynamic braking, and built-in Safe Torque Off (STO).
