# AutomationDirect GS23-22P0

Hardware · `GS23-22P0` · verification: source checked

The GS23-22P0 is a DURApulse GS20 series general-purpose AC variable frequency drive. It operates from 230 VAC with three-phase or single-phase input and provides three-phase output for induction or permanent magnet AC motors. It supports SVC, V/Hz, FOC and torque control modes and includes RS-485 Modbus communication, integrated dynamic braking and built-in Safe Torque Off.
