# AutomationDirect GS23-52P0

Hardware · `GS23-52P0` · verification: source checked

The GS23-52P0 is a DURApulse GS20 series general purpose AC variable frequency drive from AutomationDirect. It accepts 3-phase 575 VAC input and runs 3-phase induction or permanent magnet AC motors at 2 hp, using SVC, V/Hz, FOC or torque control modes. It is an enclosed B1-frame unit with RS-485 and USB B ports, integrated dynamic braking and built-in Safe Torque Off (STO).
