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.
