Danfoss VLT Common AC Fact sheet

Fact Sheet

VLT® Common AC Drive Modules

Build cabinets exactly how you need them, using VLT® common AC drive modules. By using multiple
high power drives connected in parallel, you can achieve greater power sizes in a modular solution.

VLT® common AC drive modules
comprise sets of two to four VLT® high
power drives connected in parallel,
with 6-pulse and 12-pulse variants.

A reference design for the cabinet of
the drives has been made using the
Rittal TS8 enclosure. This reference
design makes it easy for panel builders
and machine builders to build their
own cabinets, worldwide.

Reliability

Enjoy long drive lifetime and save on
extra components, with integrated
fuses and DC coils. The high-power
drive modules are delivered with these
components built-in as standard.

Increase uptime with the Reduce Run
functionality. This function enables the
system to run at part load even if one of
the drive units fails.

Back-channel cooling

A unique design uses a ducted back
channel to pass cooling air over heat
sinks with minimal air passing through
the electronics area. This design allows

90% of the heat losses to be exhausted
directly outside of the enclosure. Back­channel cooling improves reliability and
prolongs life by dramatically reducing
temperature rise and contamination
of the electronic components. There is
an IP54 seal between the back-channel
cooling duct and the electronics area of
the VLT® drive.
