Voltage and frequency matching
Working range of the voltage matcher
If the voltage U1 is in the range between Umin and Umax and the voltage U2 is greater
than U0max the adjusting commands are released. The direction of the adjusting
commands depends on the polarity of
U.
As an additional condition, both frequencies must be in the range fn
5 Hz.
