Description
The Danfoss VLT 6552 is a 400 kW frequency converter from the VLT 6000 HVAC series for 3 x 380-460 V supplies. Danfoss's VLT 6000 HVAC design guide gives it an output current of 745 A at 380-415 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.
Application: HVAC fan and pump speed control
Used with: Three-phase AC motors
What is the VLT 6552 380-460 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.
Key features
- 400 kW typical shaft output
- Output current 745 A at 380-415 V
- Mains supply 3 x 380-460 V
- Discontinued by Danfoss; successor iC7-HVACR
