I'll have to set up the test again and measure voltage drop across the
leads and the voltage directly at the power supply supply terminals.

Good that you pointed that out to me. I ran the test again. The
voltage at the power supply terminals never dropped below 15.25 vdc with
up to 3 amp load applied. When will I learn... darn those clip leads
got me... again.

power supply for FE-5680A on eBay

Thank you this is valuable info. I noticed that an effort is underway to
centralize info on the 5680. Would be nice if some one with time and software
expertize would combine all the information. I cut and paste what ever I
find on the list

With the # of units in the hands of list members it makes sense to
coordinate tests, characterizing the unit.
The PICTIC is probably the only other device having that kind of
penetration.

I just received two of these

Unloaded voltage is ~15.5vdc. At 700 ma voltage drops to 14.3 volts and
with 2 amp load drops
I used a variable voltage bench supply to experiment. tried low
voltage like you are seeing on my FE5680 and I never got a lock. The
FE5680A spec sheet says 15 to 18 volts and I think you can get buy
with 14.5V. i tried 12.5 and got nothing
I did not test to find the breaking point But 1/2
Hi
I think you would want something with better regulation to really get the Rb to
perform well.

I think it is important. The specs say 15-18V.
So I would not drop below the spec. Though interestingly pretty much
everything inside the system is using switching supplies so perhaps there
is more room.
The gtood thing about the switchers is that as the input V goes up current
should go down if
One of the regulators (the one that runs the lamp and lamp heater) is
running at 13.8V and has a 500mV dropout voltage, so there is very
little (~ 700mV) headroom. The one that runs the cell heater is about
a volt lower and the one that runs the analog circuits is set to 8.8V,
so has plenty of
15 matches
