to +10%
1) The adjustable frequency drive can run at -25% input voltage with reduced performance. The maximum output power of the
adjustable frequency drive is 75% if input voltage is -25% and 85% if input voltage is -15%.
Full torque cannot be expected at AC line voltage lower than 10% below the lowest rated supply voltage of the adjustable
frequency drive.
Supply frequency 50/60 Hz ±5%
Maximum imbalance temporary between line 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) ≤7.5 kW (10 hp) Maximum two times/minute
Switching on input supply L1, L2, L3 (power-ups) 11–22 kW (15–30 hp) Maximum one time/minute
The unit is suitable for use on a circuit capable of delivering less than 5000 RMS symmetrical Amperes, 480 V maximum.
