AutomationDirect DURApulse GS4-42P0

The GS4-42P0 is a DURApulse GS4 series AC variable frequency drive in a NEMA 1 enclosure, rated 2 hp with a 460 VAC three-phase input. It controls three-phase induction motors in either sensorless vector (SVC) or V/Hz mode and has integrated dynamic braking. An RS-485 port carries Modbus RTU, Modbus ASCII and BACnet, and optional EtherNet/IP and Modbus TCP cards can be added.
