# AutomationDirect GS23-20P2

Hardware · `GS23-20P2` · verification: source checked

The GS23-20P2 is a DURApulse GS20 series general purpose AC variable frequency drive in an enclosed A1 frame. It runs on a 230 VAC supply with either 3-phase or 1-phase input and a 3-phase output, rated 1/4 hp on 3-phase input and 1/10 hp on 1-phase input. It provides SVC, V/Hz, FOC and torque control modes, RS-485 communication, integrated dynamic braking and built-in Safe Torque Off.
