Specifications
8.2 Mains Supply
Mains supply (L1, L2, L3)
Supply voltage
Mains voltage low/mains voltage dropout:
During low mains voltage or a mains dropout, the frequency converter continues until the DC-link voltage drops below the
minimum stop level. The minimum stop level corresponds typically to 15% below the frequency converter'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
Maximum imbalance temporary between mains phases
True power factor (λ)
Displacement power factor (cos Φ) near unity
Switching on input supply L1, L2, L3 (power-ups)
Environment according to EN60664-1
The unit is suitable for use on a circuit capable of delivering not more than 100000 RMS symmetrical Amperes, 480/600 V.
