AutomationDirect DURApulse GS33-41P0

The GS33-41P0 is a DURApulse GS30 series AC variable frequency drive in an enclosed A3 frame. It takes 460 VAC three-phase input and drives three-phase induction or permanent-magnet AC motors at 1 hp, using SVC, V/Hz, FOC, encoder or torque control modes. It has an RS-485 (RJ45) and USB B port speaking Modbus RTU or Modbus ASCII slave, plus onboard analog and discrete I/O and integrated dynamic braking.
