澳洲MEPS要求只是针对一次只有一路输出的电源,有两路输出的话是要有选择开关的.如果两路同时输出的话,应该是不用做MEPS的测试的.这是个人对标准的理解

A single output external power supply which is covered by MEPS is defined as a unit which:& ^4 G8 g; R7 B; ^6 z/ {  \
. z& t  [2 z  F
has an input from mains supply (usually 110 V, 60 Hz; 230 V, 50 Hz; 240 V, 50 Hz or a range including some or all of these input conditions); and 0 v2 J# o: @, ?1 }% G
has one ELV output (either a.c. or d.c.) that is either at a fixed voltage or user selectable through a selector switch; and

is contained in a separate physical enclosure from the end-use product (i.e. the housings of the power supply and its associated product are different, not their retail packaging); and % Z7 N" p" j% }/ ^* ]6 G/ F
is connected to the end use product via a hard-wired or removable male/female electrical connection, cable, cord or other wiring; and * E! Q, t1 X# `$ W3 m, [; I) M
does not have batteries or battery packs that physically attach directly to the power supply unit (including those that are removable e.g. a battery pack for a portable electric drill); and
