General Technical Data - Frequency Converter
Mains supply (L1, L2, L3)
Supply voltage 380–480 V +5%
Mains voltage low/mains drop-out:
During low mains voltage or mains drop-out, the frequency converter continues until the intermediate circuit voltage drops
below the minimum stop level, corresponding to 15% below the lowest rated supply voltage. Power up and full torque cannot be
expected at mains voltage lower than 10% below the lowest rated supply voltage.
Supply frequency 50/60 Hz ±5%
Max. imbalance temporary between mains phases 3.0% of rated supply voltage
True power factor (λ) > 0.98 nominal at rated load
Displacement power factor (cosφ) near unity (> 0.98)
THiD < 5%
Switching on input supply L1, L2, L3 (power-ups) maximum once/2 min.
Environment according to EN60664-1 overvoltage category III/pollution degree 2
The unit is suitable for use on a circuit capable of delivering not more than 100.000 RMS symmetrical Amperes, 480/690 V
maximum.
