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 is an external power supply?
External power supplies that do not use a cable, cord, plug or wiring to connect with a product, such as induction chargers. Devices capable of multiple output voltages that are not user-selected, such as 'quick charge' units — these devices change the output voltage depending on the end-use product being connected.
Do external power supplies need to be tested?
functions. Specifically, in the December 2019 NOPR regulatory text, section 4(h) stated: “(h) While external power supplies must be tested in their final, completed the functionality of the external power supply itself. Test the external power supply in its that are shipped with it).” Id. at 84 FR 67125.
What voltage should an external power supply be marked with?
An external power supply must be marked with what it achieves at 230 V AC, unless the nameplate input voltage is 240 V AC only, in which case it must be marked with what it achieves at 240 V AC. Alternatively, an external power supply can have multiple performance marks, but each mark must be qualified with the voltage it applies to.
Should a sentence be added to the definition of an external power supply?
throughout 10 CFR part 430, including 10 CFR 430.32. Id. at 84 FR 67115. However, in December 2019 NOPR. 86 FR 60376, 60382. DOE noted that as these definitions were largely remaining in 10 CFR 430.2, the proposal to add a sentence to the definition of an external power supply would also no longer be required.
