AutomationDirect DURApulse GS33-2040

The GS33-2040 is a DURApulse GS30 series enclosed AC variable frequency drive rated 40 hp with three-phase 230 VAC input and output. 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 (RJ45) port and a USB B port, with Modbus RTU or Modbus ASCII slave communication, and requires an external dynamic braking unit.
