Danfoss' VLT Automation VT Drive was engineered to save energy, reduce upfront and operating costs and maximize uptime in industrial variable torque fan, pump, blower and compressor applications. They are available for 240 and 480 VAC single- and three-phase, or 575 and 690 VAC three-phase operation with one-half to 1,400 hp. They also include a wide range of industrial enclosure options to support varied performance needs.
A smart logic controller eliminates ancillary equipment to reduce installed costs, and main disconnects and integral fusing can further reduce installation costs by cutting panel space requirements. Dedicated pump functions can simplify programming and commissioning. An optional one-wire Safe Stop can reduce installed costs for applications with safe operation requirements.
All VLT Automation VT Drives feature an integrated DC link to eliminate the need for external filters, along with intelligent heat management to remove excessive heat and promote maximum drive operating life. An ambient temperature rating of 50°C without derating eliminates the need for expensive cooling add-ons.
VLT Automation VT Drives provide autotuning of PI-controllers to eliminate the potential for tuning, and password protection reduces the potential for unauthorized changes to the drive settings. They are available in a variety of industrial enclosures, from protected chassis to IP66 (NEMA 4X indoor), suitable for harsh washdown environments without the need for customized panels. These drives provide multiple language support to display all information in a user-selected language.
