Electrical Data, Series 320 W
If not otherwise specified, all entries are maximum values and are valid for an operating temperature range of 0 to 50 °C,
nominal power range and a line voltage range of 230 V ± 10% after a warm-up period of 30 minutes.
1) Typical values are increased by a factor of approximately 1.2 in the functional line voltage input range of –10% to –15%.
