6 FAQs about [Portable Power Supply Implementation Standards]

What are the labeling requirements for external power supplies?

Labeling requirements will be required to meet the same International Efficiency Marking Protocol for External Power Supplies Version 3.0 as the current Level V standard. Globally, it is expected that other nations will soon follow suit with this standard.

What are Energy Star standards for external power supplies?

It started with relatively simple ENERGY STAR standards for external power supplies in the 1990s. Today, there are standards tailored for the specific operating conditions of various applications, ranging from data center power supplies to white goods, LED light bulbs, electric vehicle battery chargers, photovoltaic inverters, and others.

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.

When did power supply efficiency and no-load power draw become mandatory?

The global regulatory environment surrounding the legislation of external power supply efficiency and no-load power draw has rapidly evolved over the past decade since the California Energy Commission (CEC) implemented the first mandatory standard in 2004.

What is the average efficiency of a power supply?

The average efficiency is based on the average of the efficiencies of the power supply taken at 25, 50, 75 and 100% loads. As I mentioned earlier, the DoE average efficiency standard (Table 4) is not as stringent as the CoC standard, and does not include a 10% load efficiency requirement.

Who enforces a Level V power supply standard?

The European Union is currently the only governing body to enforce compliance to the Level V standard, though most external power supply manufactures have adjusted their product portfolios to meet these requirements.
