About the Danfoss VLT 6122 525-600 V

The Danfoss VLT 6122 is a 90 kW frequency converter from the VLT 6000 HVAC series for 3 x 525-600 V supplies. Danfoss's VLT 6000 HVAC design guide gives it an output current of 137 A at 525-550 V; the full electrical data from the design guide is listed below. Danfoss's product page states that the VLT 6000 has reached the Inactive phase of its lifecycle, meaning it is discontinued and no longer in production, and names iC7-HVACR as its successor.

What is the VLT 6122 525-600 V used for?

It controls the speed of fans, pumps and compressors in building HVAC systems: air handling units, cooling towers, chilled- and hot-water pumps. A failed unit stops the fan or pump it drives.

Lifecycle and successor

Discontinued.

OEM successor: iC7-HVACR

Before you order

What to photograph or confirm so the right unit is quoted.

Read the full type code on the drive's label (it starts VLT6122, followed by the voltage, enclosure, filter, display and option codes) and send it complete: the options differ between otherwise identical 6122 units.
