Grid conditions
Supply voltage
Mains voltage low/mains drop-out:
During low mains voltage or a mains drop-out, the filter continues until the DC-link voltage drops below the minimum stop level,
which corresponds to 15% below the filter lowest rated supply voltage. Full compensation cannot be expected at mains voltage
lower than 10% below the filter lowest rated supply voltage. If mains voltage exceeds the filter highest rated voltage, the filter
continues to work but harmonic mitigation performance is reduced. The filter does not cut out until main voltages exceed 580 V.
