Danfoss VLT IP55 and IP66 frequency drives

Compact IP55/IP66 VLT® drive down to 0.25 kW

09 November 2009
Danfoss Drives present a compact A4 enclosure in protection class IP55/66 in the FC series down to 0.25 kW.

The new frame size covers:

VLT HVAC Drive:
1.1 – 2.2 kW / 200 – 240 V and
1.1 – 4.0 kW / 380 – 480 V

VLT AQUA Drive:
0.25 – 2.2 kW / 200 - 240 V and
0.37 – 4.0 kW / 380 – 480 V

VLT AutomationDrive:
0.25 – 2.2 kW / 200 - 240 V and
0.37 – 4.0 kW / 380 – (480)500 V

Smaller size, easier to install

The A4 frame size presents a more compact solution for customers that until now have used the A5 frame in the same power range.

The advantage of the new A4 frame size are :

  • Smaller mechanical size (32%)
  • Lighter weight (9.4 kg)
  • Easier mounting and installation for customers (outside fastening holes)
  • Easy line connection (45° connector)
  • No external fan in 0.37 – 1.5 kW /380-500V and 0.25 – 0.75 kW / 200 - 240V
  • Ambient temperature: 50°C continuously (only drive on the market!)
  • Optional mains switch
  • Threaded cable entry holes for ‘metric areas’
  • Smooth cable entry holes for conduit installations
  • Easy fieldbus connection
  • Compatible with Ethernet based fieldbus options
  • Same internal hardware and software as for A5
  • All options designed for placing in A and/or B slot(s)

In contrary to the frame size A5 the new A4 frame size does not have space for C options in the drive. For application that require a C option, the A5 frame is still the best solution. 

VLT Soft Starter MCD 500

The new intelligent VLT® Soft Starter MCD 500

The Danfoss VLT Soft Starter MCD 500 is a new soft starter in the power range from 7.5 to 800 kW (21 - 1600 A) with sofisticated start- and stopfunctions. 

New in the MCD 500 is the Adaptive Acceleration Control (AAC) function. This function developed by Danfoss adds intelligence to the soft starter. By continuously measuring the motor current and calculating the actual load, the MCD 500 fully automatically adjusts the start and stop profiles to obtain the best possible acceleration and decelaration for your application.
