Electrical Data for 120 W Models
 Unless otherwise specified, all entries are maximum values and apply within an operating
temperature range of 0 to 50C, within the nominal power range and the nominal line
voltage range of 230 V
10% after a warm-up period of 30 minutes.
 Percentages make reference to the respective setting value or measured value.
1)
Specified values are increased by a factor of approximately 1.2 within the functional range for line voltage, namely -10% to -15%.
