Hardware · `GS4-47P5` · verification: source checked

The GS4-47P5 is a DURApulse GS4 series AC variable frequency drive rated 7-1/2 hp with a 460 VAC three-phase input and output. It controls three-phase induction motors in either sensorless vector control (SVC) or V/Hz mode and has an output frequency range of 0.1 to 599 Hz. It is a NEMA 1, frame size A unit for panel or wall mounting with an RS-485 port, integrated dynamic braking and built-in Safe Torque Off.
