AutomationDirect GS31-22P0

The GS31-22P0 is an enclosed DURApulse GS30 series AC variable frequency drive rated for 230 VAC single-phase input and 3-phase output, 2 hp with 1-phase input. It controls 3-phase induction and permanent magnet AC motors using SVC, V/Hz, FOC, encoder or torque control modes. It provides an RS-485 (RJ45) port and a USB B port, integrated dynamic braking, and connections for optional communication, encoder and I/O modules.
