Standards for outdoor power supply exported to Europe and America

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.

Which countries adopt voluntary and mandatory external power supply standards?

Since then, the US, European Union, China and other countries adopted both voluntary and mandatory external power supply standards as part of energy conservation legislation. Table 1 shows a breakdown of some of the current voluntary and mandatory standards by region.

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 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.

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.

When will external power supplies become law?

Although there is not an oficial timeline for these voluntary standards becoming law, Original Equipment Manufacturers (OEMs) who design external power supplies into their products would best be served to future-proof their designs to the latest regulations to ensure that they are in compliance in each region where their product is sold.
