Standard panels provide complete machine control
Compact standard enclosures provide complete control in nearly any industrial application that utilises variable frequency drives for machine and process control.
Powerful variable frequency drives halve in size
Largest Danfoss variable frequency drives now offer more power in half the size of previous models and provide reliable and accurate operation at an impressive 98% operating efficiency.
Specifically engineered to satisfy the full constant or variable torque demands of virtually any industrial process applications, the new VLT 5000 Series drives are available in 125-500HP (380-500V AC) and 40-350HP (525-690V AC).
Also available in the new sizes is the FLUX version of the VLT 5000 Series, which provides servo-like performance using standard asynchronous AC motors.
For variable torque applications, VLT 4000 VT Series dedicated variable torque drives are now available in 100-400HP (525-600V AC).
These drives are available with three distinct enclosures: Chassis/IP00, NEMA1/IP21 and NEMA12/IP54, which has the smallest available footprint of the world's top five competitive units available today.
Modular construction allows users to buy only what is needed, and operating software and options facilitate easy retrofitting.
The optimised design simplifies installation and reduces the overall number of components for ease of use and maximum reliability and up-time.
Additional features and options include: built-in Class A2 RFI filtering as standard; integral disconnect with option of available fuses; power termination design for easy installation, accepting single box lug or dual cable legs; logic routing with tie-down provisions to simplify installation and protect against noise disturbance; and ambient temperature ratings of 40-45 deg C in VT mode, 50 deg C with changes in switching pattern.
Danfoss is a leading manufacturer of precision mechanical and electrical components, with locations in more than 120 countries.
Danfoss created the VLT name when they introduced the world's first mass-produced VFD in 1968, and the name has set the standard for high performance quality variable frequency drives ever since.
