Hi all,
The power supply that I ordered from ebay is a 15Volt 2Amp switcher as
follows:
15V 2A 30W Single Output Switching Power Supply

cost AU$13.00 inc postage.
Its small and easy

The Tech Manual does not call for heat sinking (unless I missed something).

The bottom has a plastic sheet between the circuitry and bottom plate.
It appears the unit was expected to be rather hot when running.

A heat sink may not be required, per se, although I would expect that a
larger thermal mass and/or thermal regulation via a closed loop fan
controller will help smooth out/stabilize temperature effects.

Maybe the test would be to measure the current draw over temperature,
when the box thinks it is warm enough it will stop heating the cell

As I understand it, the physics package needs to get quite hot
to work.
I would expect the physics package to be well insulated and off
by itself, but this doesn't seem to be the case.

I don't know what all the grief is about a power supply to run the 5680
units. I have three 5380/Trimble GPs units in various locations being
powered by Mean Well power supplies from Mouser. # 709-T40C for about 50
bucks - 75 bucks for one with more current. It is a switching ps but seems
clean

Have to agree thats very attractive. Few bucks for shipping and you are
done.

Ditto - this is the same P/N of the one I have. It takes both a 15 V and a 5 V
supply.
The pin numbers reported here earlier are correct:
PIN 1: INPUT +15V to +18V
PIN 2:

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