Line Reactors on VFD line inputs protect drives from current spikes and reduce harmonics. On VFD outputs, line reactors or output filters protect motors and are recommended for VFDs used with non-inverter-duty motors. For motor wiring up to 100 feet, a line reactor is acceptable. For distances from 100 feet to 1,000 feet, an output filter is recommended.
Line reactors have universal mounting feet with multiple mounting slots and can replace most line reactors using existing mounting holes. Output filter units combine line reactor and resistor-capacitor filter circuit to provide protection against voltage wave reflection, especially on long motor cable runs."
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.
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.
Drive configuration and programming software 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.
Option cards are available to increase the available I/O or add communications capabilities.
Replacement cooling fans for drives are direct replacements, dimensionally and electrically equivalent to the original part. Fan electrical loading is included in the input amperage ratings of the drives, and the DC voltage to power the fans is provided internally by the drives.
Remote keypads, bezels, cables, backup power supplies, memory modules, DIN rail mounting adapters and other accessories are available to complete the installation of your VFD.
Conduit box kits bolt to the bottom of a VFD to provide conduit entry and a/ NEMA 1 rating without the need to install in a separate enclosure. Flange mounting kits extend the heat sinks on the back of the drive through the rear of the enclosure. EMC shield plates allow motor lead shields to be grounded at the drive.
NEMA 4X disconnect switch provides local on/off control to the GS20X drive.
Fuses, fuse kits and replacement fuses are available for Micro, General Purpose and High-Performance AC drives.
