AutomationDirect GS3-AC AC General Purpose Drive

The AutomationDirect DURApulse GS3-AC AC General Purpose Drive is a 230V, 20 HP variable-frequency drive designed for robust three-phase motor control in industrial settings. As part of the GS3 family, it features sensorless vector control with autotune and offers optional encoder feedback for tighter speed regulation, along with a versatile I/O set: three analog inputs, one analog output, eleven digital inputs, and four programmable outputs (three digital and one relay), plus a dedicated digital frequency pulse output. Communications include RS-485 Modbus with Ethernet optional, and parameter management is facilitated by a removable HIM keypad that can store up to four programs. The drive is UL/CE listed and configured for 230 VAC three-phase power, aligning with the GS3’s 5–50 HP range for 230 VAC models. For setup and diagnostics, AutomationDirect provides a GS3 user manual and software support to aid configuration, tuning, and monitoring of general-purpose speed control for three-phase motors. In short, it combines advanced control features with a rich I/O footprint in a compact 230V, 20 HP package suitable for general automation tasks where reliable V/Hz or sensorless speed control is desired.
