The VLT

Compressor Drives utilize and combine Danfoss

design and manufacturing expertise. Our extensive
application knowledge of refrigeration, air conditioning,
and motion controls ensures an optimized product design
and package solution:

•

A “plug & play” solution

•

Operational efficiency

•

Flexibility & best control accuracy

•

Innovative and reliable solution

The frequency converter is 100% preset for speed open
loop configuration with 0-10 V reference corresponding to

1800-5400 RPM for CDS 302 and 1500-6000 RPM for CDS
303.
