What is EuP (ErP) Mode and how can it help to save power?
Posted by Jack Ni on 20 May 2014 01:33 AM

ErP, Energy-related Products, are products that use energy, or that do not use energy but have an indirect impact on energy consumption, such as water using devices, building insulation products, windows, etc. Compared to ErP, Energy-using Products (EuP) are products which are dependent of energy input (electricity etc.) All ErP and EuP are subject to energy efficiency requirements.

In November 2009, the Eco-Design Directive EuP was replaced with the new energy-related products directive (ErP) 2009/125/EC. The old directive for energy using products only covered products that used energy, such as washing machines or computer. The new ErP-Directive covers products under the old EuP Directive as well as products that are energy-related and do not directly use energy such as water-saving taps and showerheads.

The EuP/ErP feature in our system follows ErP Lot 6 2013 compliant which requires a PC system should not consume more than 0.5 W during “off state” or “standby.” In other words, this function only works when system is shut down or in system sleep mode (S3) and the power consumption should be less than 0.5 W.
