Input line reactors protect the AC drive from transient overvoltage conditions typically caused by utility capacitor switching. Input line reactors also reduce the harmonics associated with AC drives and are recommended for all installations.
These components are compatible with various DURApulse, Toshiba GS series, and WEG drives (check specifications for selection).
Newest Additions!
Output line (load) reactors protect the motor insulation against AC drive short circuits and IGBT reflective wave damage, and also allow the motor to run cooler by "smoothing" the motor current waveform. They are recommended for operating "non-inverter-duty" motors, and for any motors where the length of wiring between the AC drive and motor is less than 100 feet.
For AC Drive-to-Motor wiring distances over 100 feet, use of the VTF series output filter is recommended.
Newest Additions!
Braking resistors are used to increase the braking torque of the AC drive, for frequently repeated ON-OFF cycles of the AC drive, or for decelerating a load with large inertia. Braking resistors are compatible with various AC drives (check specifications for selection).
Larger AC drives also require that dynamic braking units be used in conjunction with the appropriate braking resistors. Braking units are available for certain DURApulse drives.
Newest Additions!
Filters reduce electromagnetic interference and offer high performance for use in a variety of drive applications where long motor supply cable runs are necessary and where compliance with industrial noise limits is required.
Zero phase reactors, (aka RF noise filters) help reduce radiated noise from the inverter wiring and are effective for noise reduction on both the input and output sides of the inverter.
Components are compatible with various GS series, WEG, or other brands of drives (check specifications for selection).
Newest Additions!
Option cards are available to increase the I/O or add communications capabilities. Modules are available for various DURApulse, Toshiba, IronHorse, and WEG drives.
Options include (check for compatibility with specific drives):
Newest Additions!
Drive configuration and programming software (available as a free download or on USB) allows the user to connect to a VFD from a PC for fast, convenient setup and/or programming of a built-in PLC, and offline storage of (multiple) configuration parameters.
