Note
With effect 7th January 2010 the so-called standby regulation came into force within the European Union. Reducing the power consumption until 2020 by 75% in the standby mode is the aim of this
regulation. Due to that regulation electrical home appliance, communication and office equipment aren’t allowed to spend more than 2 Watt in the standby mode. For devices which are simply
reactivated only 1 Watt is allowed. From 2014 on the values will reduce further on.
For those standby applications SMPS are needed that are compact and efficient but don’t exceed the requested consumption either. The high voltage version of the power inductors WE-PD2 is
especially designed for such applications. A special layout combined with a complex test setup guarantees the requested withstand voltage of the rectified supply voltage of 400 V
