Danfoss variable frequency drives have
more power
High power variable frequency drives by Danfoss Drives not only deliver high power performance, they facilitate ease-of-use by sharing a common platform with smaller drives from the same maker.
Danfoss Drives VLT Series Variable Frequency Drives are now available with power through 1350HP in 460 and 690V AC F1 frame models deliver power up to 1050HP in an 86.8in x 55.1in x 23.9in footprint

* Common drive platform - these high power variable frequency drives share a common platform with smaller Danfoss drives.
Proven power electronics promise reliable operation, said Danfoss to manufacturingtalk, 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.
A Class A1 RFI filter (optional class A2) reduces EMI/RFI without the need for external filters.
Additional features include the following.
* DC-link reactors to reduce harmonics without external AC line reactors.
* DC-link fuses that provide independent protection of inverters.
* Coated PCBs provide extra protection in potentially corrosive environments.
High power F frame size VLT Series variable frequency drives also feature a novel cooling design that uses 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.
This feature improves reliability and prolongs drive life by dramatically reducing temperature rise and contamination of electronic components, said Danfoss.
A number of power, monitoring, enclosure, filtering, control and convenience options and accessories are available to enhance performance and operation.
* About Danfoss - Danfoss is a leading manufacturer of precision mechanical and electrical components, with locations in more than 120 countries.
Danfoss created the VLT name when it 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.
