*) C = power loss into coolant, A = power loss into air, T = total power loss.
The enclosure class for all Vacon NX liquid cooled frequency converters is IP00.
***) Mains voltage 640-1200 VDC for NX_8 inverter units.
I = Thermal maximum continuous RMS current. Dimensioning can be done according to this
th
current if the process does not require any overloadability or the process does not include any load
variation.
I = Low overloadability current. Allows +10% load variation. 10% exceeding can be continuous.
L
I = High overloadability current. Allows +50% load variation. 50% exceeding can be continuous.
H
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
power losses are worst case losses.
