*) C = power loss into coolant, A = power loss into air, T = total power loss.
The enclosure class for all VACON
®
NX Liquid-Cooled AC drives is IP00.
***) Mains voltage 640-1200 VDC for NX_8 inverter units.
I
th
= Thermal maximum continuous RMS current. Dimensioning can be done according to this
current if the process does not require any overloadability or the process does not include any load
variation.
I
L
= Low overloadability current. Allows +10% load variation. 10% exceeding can be continuous.
I
H
= High overloadability current. Allows +50% load variation. 50% exceeding can be continuous.
All values with cosϕ = 0.99 and efficiency = 97.5%.
*) c = power loss into coolant; a = power loss into air; T = total power loss.
All power losses obtained using max. supply voltage, I
th
and switching frequency of 3.6 kHz. All
power losses are worst case losses.
