Energy storage equipment requires external AC power supply

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 minimum energy performance standards for external power supplies?

The Minimum Energy Performance Standards for external power supplies are: for products with AC outputs — the requirements mentioned in Clause 2.2 of AS/NZS 4665.2:2005 (Average Active Mode Efficiency). For more information, see subsection 7 (1) of the Determination. To be registered as a ‘high efficiency’ product, a power supply must meet either:

What are external power supplies?

See Regulated products for details about past consultations, related materials and next steps. External power supplies are also called power adaptors, plug-packs or power packs. They are used to recharge or power products such as laptops, mobile phones, modems, printers, and other extra low voltage products both fixed and portable.

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.
