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 3.1.1, the maximum working voltage in Section 3.1.1 shall be regarded as the
rated voltage.
