New Zealand - Consultation on Energy Efficiency Requirements for External Power Supplies

​The notified consultation document presents policy options to:

 - Increase the Minimum Energy Performance Standards (MEPS).

 - Widen the scope of external power supplies covered.

 - Reference international test standards.

Three MEPS levels are considered in the consultation document:

 - International Efficiency Marking Protocol (IEMP) III (current MEPS)

 - International Efficiency Marking Protocol (IEMP) VI

 - US levels, proposed International Efficiency Marking Protocol (IEMP) VII

Widening the scope considered in the consultation document:

 - Include USB Power Delivery devices which automatically change their output voltage depending on the External Power Supply end device.

The international test standards considered are:

 - EN  50563:2011+A1:2013  External  a.c. - d.c. and a.c. - a.c. power supplies  – Determination of no-load power and average efficiency of active modes

 - United States Code of Federal Regulations, Title 10, Part 430, Subpart B, Appendix Z Uniform Test Method for Measuring the Energy Consumption of External Power Supplies​
