AutomationDirect GS33-4100

The GS33-4100 is an enclosed DURApulse GS30 series AC variable frequency drive rated for 100 hp on a 460 VAC three-phase input. It controls three-phase induction and permanent magnet AC motors using SVC, V/Hz, FOC, encoder or torque control modes, with an RS-485 port running Modbus RTU or Modbus ASCII slave protocols plus a USB B port. It mounts on a panel or wall, uses spring clamp terminals, and accepts optional communication, encoder and I/O modules.
