Applications
Timing
Initial turn-on
The line voltage must be pre-
sent at least 1 period before
the input voltage is applied.
Repetitive turn-on
The input voltage must be
lower than the drop out volt-
age limit at least 1 period be-
fore it is reapplied.
As transformers can have va-
rying stray inductances and
stray capacitances, it is al-
ways advisable to use external
overvoltage protection.
