All the qualities experienced since Danfoss put the first mass-produced drive on the market in 1968 are still to be found in the new VLT high power range
In Danfoss’ new high power drives all the advantages from the lower power drives, including user-friendly commissioning and operation are present. A host of advanced and yet easy-to-use features and options is built in and tested from factory and meet any specification your application require.
High efficiency
VLT high power drives are energy efficient. 98% of the power is transferred to the motor, preventing overheating and wasted energy.
Heat Management
Only 2% of the energy is lost through the drive. Although this is a small percentage, with large drives this heat loss must still be managed. Since VLT drives transmit 85% of the excess heat through the back-channel heat sink, it is removed from the drive, the panel, and the environment.
Only 15% of the excess heat needs to be removed from the drive electronics cabinet and control room.
Save space
The compact design of the VLT drives – and high power drives in particular – makes them easy to fit in even small installation spaces. Built-in filters, options and accessories facilitate this compact installation.
DC coils are built in and eliminate the need for external AC-coils for harmonic suppression. Optionally, built-in RFI filters are available in the whole power range in most series. Input fuses and mains switch (disconnect) are available with standard enclosures, that are available with IP 21 (NEMA 1) or IP 54 (NEMA 12) rating.
Save time
VLT drives are designed to save time in installation, commissioning and maintenance.
The intuitive user interface --includes the award-winning control panel (LCP) in the new series and is the same for the full power range. If you are acquainted with the VLT user interface, you are able to set up and operate the new high power drives immediately.
Time is also saved in installation of additional options due to the plug-and-play principle.
The usual robust design of the VLT drives and efficient monitoring make VLT drives almost maintenance free.
