7.2 Line Power Supply
Line power supply (L1, L2, L3)
Supply voltage 200–240 V ±10%
Supply voltage 380–480 V ±10%
Supply voltage 525–600 V ±10%
Supply voltage 525–690 V ±10%
AC line voltage low/line drop-out:
During low AC line voltage or a line drop-out, the adjustable frequency drive continues until the intermediate circuit voltage
drops below the minimum stop level. Typically, this corresponds to 15% below the lowest rated supply voltage of the adjustable
frequency drive. Power-up and full torque cannot be expected at AC line voltage <10% below the lowest rated supply voltage of
the adjustable frequency drive.
Supply frequency 50/60 Hz +4/-6%
The adjustable frequency drive power supply is tested in accordance with IEC61000-4-28, 50 Hz +4/-6%.
Maximum imbalance temporary between line power phases 3.0% of rated supply voltage
True power factor (λ) ≥0.9 nominal at rated load
Displacement power factor (cosφ) near unity (>0.98)
Switching on input supply L1, L2, L3 (power-ups) ≤7.5 kW maximum 2 times/min.
Switching on input supply L1, L2, L3 (power-ups) 11–90 kW maximum 1 time/min.
Environment according to EN 60664-1 Overvoltage category III/pollution degree 2
The unit is suitable for use on a circuit capable of delivering not more than 100000 RMS symmetrical Amperes,
240/480/600/690 V maximum.
