By supplying the motor with a sinusoidal voltage waveform, the switching acoustic noise from the motor is also eliminated.
Features & Benefits
• Supplies the motor with a sinusoidal voltage waveform
• Eliminates over-voltages and voltage spikes caused by cable reflections
• Reduces electromagnetic interference by eliminating pulse reflection caused by current ringing in the motor cable. This allows the use of unshielded motor cables in some applications
• Eliminates acoustic noise in motor
• Reduces high frequent losses in motor
Enclosures
• IP 00 and IP 20 wall-mounted enclosure up to 75 A (500 V)/45 A (690 V)
• IP 23 floor-standing enclosure from 115 A (500 V)/76 A (690 V)
Range
3 x 200 – 500 V, 2.5 – 800 A
3 x 525 – 690 V, 4.5 – 660 A
Mounting
Side by side mount with the drive up to 75 A (500 V) and 45 A (690 V)
Advantages
• Compatible with all control principles including flux and VVC+
• Parallel filter installation is possible for applications in the high power range
Qulity & Design
All filters are designed and tested for operation with the VLT® AutomationDrive FC 302, VLT® AQUA Drive FC 202, and the VLT® HVAC Drive FC 102. They are rated for the nominal switching frequency of the VLT® FC series and therefore no derating of the drive is needed.
The enclosure is designed to match the look and quality of the VLT® FC series drives.
