AutomationDirect GS33-2050

The GS33-2050 is an enclosed DURApulse GS30 series AC variable frequency drive rated 50 hp on a 230 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 a 0.1 to 599 Hz output frequency range and a 2 to 15 kHz carrier frequency. Setup, monitoring and embedded ladder logic programming are handled through RS-485 (Modbus RTU/ASCII slave) or USB B connections.
