Danfoss Australia displayed
its new VLT family
of AC drives, ranging
in capacity from 0.18
kW to 1.2 MW and are
highly efficient, with
98% of the power being
transferred to the motor.
Even this small percentage
can mean significant
heat loss on a large drive,
but this is managed by
transmitting 85% of the
excess heat through the
back-channel heat sink,
removing it from the
drive, panel and working
environment. Features of
the VLT drives that minimize
installation space
include built-in DC coils
for harmonic suppression
(rather than external AC-coils), built-in RFI filters, and the
optional placing of input fuses and main disconnect switch
within the standard enclosures.
