Hardware · `GS33-2015` · verification: source checked

AutomationDirect GS33-2015 is an enclosed DURApulse GS30 series AC variable frequency drive. It accepts 230 VAC three-phase input and drives three-phase induction or permanent magnet AC motors with a 15 hp rating, using SVC, V/Hz, FOC, encoder or torque control modes. It provides RS-485 Modbus RTU/ASCII communication, integrated dynamic braking, built-in Safe Torque Off, and an IP20 enclosure.
