A parenthetical reference at the end of a comment quotation or paraphrase provides the location of the item in the public record.7 This SNOPR addresses only those comments relevant to the proposals laid out in this document; all other relevant comments will be addressed in the final rule. The regulatory text as amended by the amendments proposed in both the December 2019 NOPR and this SNOPR
is presented at the end of this document for the convenience of review of all the proposed amendments.
II. Synopsis of the Supplemental Notice of Proposed Rulemaking In this SNOPR, DOE proposes to supplement or replace those proposed amendments from the December 2019
NOPR with further amendments that would provide as follows:
1 Remove reference in the scope section of appendix Z to direct operation and indirect operation Class A

EPSs because there is no distinction in how these EPSs are tested.
2 More explicitly align the test procedure with the scope of the energy conservation standards set forth at 10
CFR 430.32w1 by excluding from testing devices for which the primary load of the converted voltage within the device is not delivered to a separate end use product.
3 Specify testing requirements for EPSs that are packaged without an output cord to provide explicitly that these EPSs are tested with an output cord that is recommended for use by the manufacturer.
4 Modify the proposal from the December 2019 NOPR to define USB
PD EPS so as to include programmable power supplies PPSs and USBPD
EPSs with optional voltages and currents; and further amend the definition of nameplate output power to specify that USBPD EPSs must be tested at the lowest nameplate output voltage, which can be as low as 3.3 volts
Commenter type Trade Association.

for PPSs, rather than at 5 volts as was proposed in the December 2019 NOPR.
Additionally, DOE is modifying the December 2019 NOPRs proposal to relocate certain definitions. Specifically, DOE is no longer proposing to relocate the definitions of Class A external power supply, basic-voltage external power supply, direct operation external power supply, indirect operation external power supply, and low-voltage external power supply at 10 CFR 430.2 rather than include them in appendix Z.
The actions proposed in this SNOPR
are summarized in Table II.1 and addressed in detail in section III of this document. Unless otherwise provided, DOE continues to propose the amendments presented in the December 2019 NOPR. To facilitate commenter review, the proposed regulatory text at the end of this document provides the proposed regulatory text from the December 2019 NOPR as modified by the proposals in this SNOPR.

TABLE IIISUMMARY OF CHANGES IN PROPOSED TEST PROCEDURE RELATIVE TO CURRENT TEST PROCEDURE AND TO
AMENDMENTS PROPOSED IN THE DECEMBER 2019 NOPR
Current DOE test procedure
December 2019 NOPR proposals
Proposed test procedure
Attribution
Specifies that the scope of the test procedure includes direct operation EPSs and indirect operation Class A EPSs.
Does not explicitly exclude testing of devices for which the primary load of the converted voltage within the device is not delivered to a separate end use product.

Not addressed

Deletes the specific reference to direct operation EPS and indirect operation Class A EPS.

Response to stakeholder comment to more explicitly define the scope of the test procedure.

Specified that components and circuits unrelated to EPS
functionality may be disconnected during testing as long as the disconnection does not impact the functionality of the EPS itself.
Proposed to move all of these definitions to the EPS test procedure at appendix Z.

Excludes devices for which the primary load of the converted voltage within the device is not delivered to a separate end use product.

Response to stakeholder comment to more explicitly define the scope of the test procedure.

Proposes to retain all of these definitions at 10 CFR 430.2 except adaptive external power supply.

Improve readability and applicability of the test procedure.

Proposed inclusion of Class A
EPS definition in appendix Z
while also retaining it in 10 CFR
430.2.

Proposes retaining Class A EPS
definition in 10 CFR 430.2 only and not include it in appendix Z.

Improve readability and applicability of the test procedure.

Does not include definitions of adaptive external power supply, basic-voltage external power supply, direct operation external power supply, indirect operation external power supply, and low-voltage external power supply. These definitions are specified in 10 CFR 430.2.
Does not include definition of Class A EPSs, which is currently specified in 10 CFR 430.2.
