11.4.1 Power Rating

Grid conditions
Supply voltage
AC line voltage low/line drop-out:
During low AC line voltage or a line drop-out, the filter continues until the intermediate circuit voltage drops below the
minimum stop level, which corresponds to 15% below the filter lowest rated supply voltage. Full compensation cannot be
expected at AC line voltage lower than 10% below the filter lowest rated supply voltage. If AC line 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 AC line voltages exceed 580 V.
