AutomationDirect DURApulse GS4-4060

The GS4-4060 is a DURApulse GS4 series open-frame AC variable frequency drive rated 60 hp with a 460 VAC three-phase input and three-phase output. It controls three-phase induction motors using either sensorless vector control (SVC) or V/Hz mode, with an 86 A amperage rating. Setup, monitoring and speed reference come from discrete and analog I/O, a keypad, or the RS-485 port, and an external dynamic braking unit is required for braking duty.
