Really??? I had never heard of a controller cutting out (it does have a heat
triggered overload sensor) with just one or two motors loading it REGARDLESS
of length of continuous running.
Wow.
I wonder why. What is your frequency in Oz? 50hz or 60hz ??? The voltage
should not matter since it's stepped down to the same input voltage by the
wall wart whether you start at 220 or 110. But I speculate (baseless
speculation except that I had 3 years of vocational electronics in high
school, most of which I've forgotten) that 50 hz makes for more work for the
capacitator to do and rougher waveforms than 60 hz... (the US is 110v and 60hz)
