Power ratings
Vacon Liquid-Cooled product range consists of both frequency converters (AC input, AC output) and in-
verter units (DC input, AC output). The following tables present the drive output values for both and an in-
dication of motor shaft power at I
th
and I
L
at different mains voltages as well as the drive losses and me-
chanical sizes. The power achieved is given as per the supply voltage.
