It will pull 35W for the first five or so minutes then the current drops
rather suddenly to about 700mA.

I have an analog amp meter on my power supply and I can see a switch over
after the unit heats up.   They must run an internal oven heater full tilt
at first then go into regulated mode.

Some one else said you can cause the FE5680 to draw more power in steady
state mode by adding heat sinking it.  Yes that works.  Seems the FE5680
wants to be at some set temperature and the heat sink means it takes more
power to keep at the set point.   I just let the fe5680 rest on a small
aluminum plate.
