VLT® 7000 Booster
All about VLT 7000
Booster
■ Acoustic noise
The acoustic interference from the frequency
converter comes from two sources:
1. DC intermediate circuit coils
2. Integral fan.
Below are the typical values measured at a distance
of 1 m from the unit at full load and are nominal
maximum values:
VLT 7002-7011 380-460 V
IP 20 units: 50 dB(A)
VLT 7016-7072 380-460 V
IP 20 units: 61 dB(A)
■ Derating for ambient temperature
The ambient temperature (T
AMB,MAX
) is the maximum
temperature allowed. The average (T
AMB,AVG
) measured
over 24 hours must be at least 5ºC lower.
If VLT 7000 Booster is operated at temperatures
above 45 ºC, a derating of the continuous
output current is necessary.
