Rated Voltage
The rated voltage is calculated from the rated power and nominal resistance by the
following formula:
= √.
Where E : Rated Voltage (V)
P : Rated Power (W)
R : Nominal Resistance ()
In case the value calculated by the formula exceeds the maximum working voltage given
in Section 3.1.2, the maximum working voltage in Section 3.1.2 shall be regarded as the
rated voltage.
