To be defined, value or description will follow later.
AC 230V
A figure displayed with the AC or DC before the value represents a nominal voltage with
standard tolerances (usually ±15%) included.
E.g.: DC 12V describes a 12V battery disregarding whether it is full (13.7V) or flat (10V)
230Vac
A figure with the unit (Vac) at the end is a momentary figure without any additional
tolerances included.
50Hz vs. 60Hz
As long as not otherwise stated, AC 230V parameters are valid at 50Hz mains frequency.
