What are the new energy conservation standards for external power supplies?
The U.S. Department of Energy (DOE) has recently proposed new energy conservation standards for External Power Supplies (EPSs). These proposed standards, known as Trial Standard Level 4 (TSL4), aim to tighten energy efficiency requirements across all types of EPSs. TSLs are a tool used by the DOE to set energy conservation benchmarks.
What are the labeling requirements for external power supplies?
Labeling requirements will be mandated to meet the same International Eficiency Marking Protocol for External Power Supplies Version 3.0 as the previous Level V standard. Globally, it is expected that other nations will soon follow suit with the DoE Level VI standard.
Do external power supplies have a power efficiency mandate?
At a global level, mandates for power efficiency exist for most consumer electronics and home appliances. External power supplies have had regulations dating back to 2004, when the California Energy Commission created one of the first mandates for efficiency of external power supplies used to power appliances or consumer electronic devices.
What are the new standards for power supply design?
In 2014, the US Department of Energy formalized their newest mandatory standard and the EU’s voluntary Code of Conduct version 5 took effect. This white paper briefly explains the US and EU’s new standards and what they mean to power supply designers.
Why do energy agencies need external power supplies?
Energy agencies around the world are concerned about growing power consumption and the amount of available deliverable energy. One of the largest demands on the world’s power grid comes from external power supplies (EPSs); these include laptop adapters and phone and tablet USB chargers/adapters.
What is the EU Code of conduct on energy eficiency of external power supplies?
The European Union published its Code of Conduct (CoC) on Energy Eficiency of External Power Supplies Version 5 in October 2013. Tier 1 efectively harmonizes the EU with DoE Level VI, noting the diferences in scope detailed below, and became efective as a voluntary requirement from January 2014, some two years ahead of DoE Level VI.
