AutomationDirect DURApulse GS4-4175

The DURApulse GS4-4175 is an open-frame AC variable frequency drive in the GS4 series. It takes 460 VAC three-phase input and drives a 175 hp motor using SVC or V/Hz control, with an RS-485 port for Modbus RTU, Modbus ASCII and BACnet communication. Built-in Safe Torque Off is included, and an external dynamic braking unit is required.
