RE: Effect of a universal power connector on Energy Star and EPEAT compliance
Hi Paul,
It should be possible to make a UPAMD spec that does not specify certain efficiencies directly but instead enables best practices for efficient design. This way UPAMD adapters should have the best opportunity to comply with existing and upcoming efficiency standards.
Another interconnected issue is that the adapter spec should be independent of energy source. The UPAMD standard should work on any energy source be it AC at fixed voltages and frequencies, variable frequencies from small AC generators, DC from vehicles and photovoltaics etc.
If certain efficiency standards becomes compulsory UPAMD spec the non-specified source of energy may no longer prevail.
Kind regards,
Per

Hi Leonard:
Since no Energy Star certification procedure currently exists for variable
output power adapters and presumably the UPAMD universal connector will be
used primarily with power adapters that are capable of providing various
output voltages, doesn't it follow that any product that uses the UPAMD
won't be able to achieve an Energy Star certification?
It's clear that ideally, the universal connector spec would be independent
of Energy Star, but doesn't the nature of it impact a product's ability to
be certified?
What vendor would opt to use a UPAMD connector if it came at the expense of
its Energy Star certification?

QUESTIONS:
* Will UPAMD take a position at all on efficiency requirements?
My suggestion is no as there are already a lot of group addressing this
issue
.
* Does UPAMD expect to provide a spec that will at least be neutral with
respect to Energy Star certification?
My suggest is also no for any reference to Energy Star certification.

compliance
Hello:
In a recent Energy Star update, the group decided to avoid inclusion of any
regulation for multi-output power adapters. They did so, primarily because
it was too difficult to compare apples to apples. While the testing
procedure for a single voltage output external power adapter is well
defined,
testing a multi-voltage output and potentially multi-port power adapter is
not so easily defined.
While the UPAMD focus is on a universal connector, is it possible that a
universal connector could have an impact on the ability of the power adapter
to meet Energy Star compliance?
QUESTIONS:
* Will UPAMD take a position at all on efficiency requirements?
* Does UPAMD expect to provide a spec that will at least be neutral with
respect to Energy Star certification?
