Overvoltage limiter (Forsmark Event)
In case of input voltage variation, independent of the input voltage gradient, the duration and its maximum value, the patented overvoltage limiter reduces the value of the DC output voltage to less than 115 % of the nominal DC voltage. The overvoltage detection is a self-acknowledging fault.
