# AutomationDirect GS23-45P0

Hardware · `GS23-45P0` · verification: source checked

The GS23-45P0 is a DURApulse GS20 series general purpose AC variable frequency drive from AutomationDirect. It accepts 460 VAC three-phase input and runs 5 hp three-phase induction or permanent magnet AC motors in SVC, V/Hz, FOC or torque control mode. It is an enclosed, C-frame, panel- or wall-mounted unit with RS-485 Modbus communication and integrated dynamic braking.
