Need More Power? Get It from Danfoss Drives' Newest High Power VLT® Series Variable Frequency Drives



LOVES PARK, IL -- Danfoss Drives VLT® Series Variable Frequency Drives are now available with power through 1350 HP in 460 and 690 VAC. F1 frame models deliver power up to 1050 HP in an 86.8 in. x 55.1 in. x 23.9 in. footprint, while F2 frame models deliver up to 1350 HP in an 86.8 in. x 71.0 in. x 23.9 in. footprint.

These high power variable frequency drives not only deliver high power performance, they facilitate ease-of-use by sharing a common platform with smaller Danfoss drives. Proven power electronics promise reliable operation, and components are accessible from the front of the unit for quick, easy serviceability and maintenance. A Rittal TS8 enclosure system in IP21 (NEMA1) or IP54 (NEMA12) enables easy system expansion, while a Class A1 RFI filter (optional class A2) reduces EMI/RFI without the need for external filters. Additional features include DC-link reactors to reduce harmonics without external AC line reactors, DC-link fuses that provide independent protection of inverters, and coated PCBs provide extra protection in potentially corrosive environments.

High power F frame size VLT Series variable frequency drives also feature a unique cooling design that utilizes a ducted back channel to pass cooling air over heat sinks, with minimal air passing through the electronics area. This allows 85% of the heat losses to be exhausted directly outside the enclosure, which improves reliability and prolongs drive life by dramatically reducing temperature rise and contamination of electronic components.

A number of power, monitoring, enclosure, filtering, control and convenience options and accessories are available to enhance performance and operation.

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.
