5 Specifications
5.1 General Specifications
Mains supply (L1, L2, L3)
Supply voltage 525-690 V -10/+5%
Mains voltage low/mains drop-out:
During low mains voltage or a mains drop-out, the frequency converters continues until the intermediate circuit voltage drops
below the minimum stop level, which corresponds typically to 15% below the drive's lowest rated supply voltage. Power-up and
full torque cannot be expected at mains voltage lower than 10% below the frequency converter’s 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) ≥0.9 nominal at rated load
Displacement Power Factor (cos ϕ) near unity (> 0.98)
Switching on input supply L1, L2, L3 (power-ups) maximum 1 time/2 min.
Environment according to EN60664-1 over-voltage 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, 500/600/690 V
maximum.
