Hardware · `GS23-40P5` · verification: source checked

The GS23-40P5 is an enclosed general-purpose AC variable frequency drive in the DURApulse GS20 series. It takes 460 VAC three-phase input and drives three-phase induction or permanent magnet AC motors, rated 1/2 hp with three-phase input. It supports SVC, V/Hz, FOC and torque control modes and includes an RS-485 port, a keypad, integrated dynamic braking and built-in Safe Torque Off.
