AutomationDirect DURApulse GS33-21P0

The GS33-21P0 is an enclosed DURApulse GS30 series AC variable frequency drive rated 1 hp with a 3-phase, 230 VAC input and output. It controls 3-phase induction and permanent magnet AC motors using SVC, V/Hz, FOC, encoder or torque control modes and includes integrated dynamic braking. Setup and monitoring are done through analog and discrete I/O, an attached keypad, and an RS-485 port running Modbus RTU or ASCII slave.
