# AutomationDirect DURApulse GS4-2030

Hardware · `GS4-2030` · verification: source checked

The AutomationDirect DURApulse GS4-2030 is a 230 VAC high-performance variable frequency drive in a NEMA 1, IP20 enclosure with frame size C. It supplies 30 hp from a three-phase input or 10 hp from a single-phase input and runs three-phase induction motors in either sensorless vector (SVC) or V/Hz control mode. It has integrated dynamic braking, built-in Safe Torque Off, and an RS-485 port supporting Modbus RTU, Modbus ASCII and BACnet.
