Comments

  • 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 VDC.
