|DURApulse - GS4 Drive Units (230 / 460 VAC SLV w/PLC)|
Variable frequency drives (VFD) enable speed control for three-phase AC motors such as those in conveyors, fans, pumps and material handling. DURApulse GS4 series AC inverters in sizes up to 300hp offer V/Hz or sensorless vector control, Safe Torque Off (STO), 100kA Short Circuit Current Rating (SCCR), a built-in logic controller and a host of other advanced features.
|AC Line Reactors|
Line reactors are recommended on GS series VFD line inputs to protect the drive from transient overvoltage conditions and reduce the effects of harmonics created by the VFD. When used on VFD outputs, line reactors protect motors from damage, allow cooler running, and are recommended when operating non-inverter-duty motors or with motor wires longer than 75 feet.
|DURApulse - GS4 Braking Options (Braking Units & Resistors)|
When a variable frequency drive decelerates an AC motor, especially one with a large inertial load attached, a braking resistor may be required to help dissipate the energy. Larger GS4 DURApulse series AC drives ( approx. 30 hp and above) also require that dynamic braking units be used in conjunction with the appropriate braking resistors.
|DURApulse - GS4 Spare Parts and Accessories|
DURApulse (GS4) drive-specific accessories include Ethernet and I/O option cards, conduit boxes and flange mount kits, replacement fans, remote keypad mounting bezels, and replacement keypads. Use GSOFT2 drive setup software and GSLOGIC PLC programming software to configure and program the drive. Cables and connectors are available for various communications needs.
