# AutomationDirect GS23-47P5

Hardware · `GS23-47P5` · verification: source checked

The GS23-47P5 is a DURApulse GS20 series general purpose AC variable frequency drive in an enclosed frame. It takes a 460 VAC three-phase input and is rated 7-1/2 hp, driving three-phase induction or permanent magnet AC motors in SVC, V/Hz, FOC or torque control mode. It provides RS-485 Modbus RTU/ASCII slave communications, a USB B port and integrated dynamic braking.
