Unless you want to run it at full power you can use any smaller supply. The cheap ebay 480 watt 24v ones or even an old laptop charger can be used too! You dont need spend lots of money. Or a server supply like expresso or steve uses?
Full stop makes that read to me 1.8 watts! But thinking about it its probably right as you say. Either way thats not cheap.
In Italy too the thousands marker is the "." and the decimal marker is the ",". So the way those specs are written is not wrong, just different from anglo-saxon. Even more confusing for me to adjust too is dates being dd/mm/yy and I still have to think twice when I see something line 8/12/2010. Is that the 8th of December or the 12th of August?
How will you connect the batteries? Anything over 12A needs Anderson.
The recommended charge rate for MK is 30A per 100Ah. So about 1/3rd capacity.
So even if you charge at 50% of capacity, which will be fine, then you are only going to use 15A of the chargers 40A caapability. So a huge power supply isnt needed.
15A X 28v = 420 Watts, plus say 10% due to efficiency loss. So a 500 watt power supply is enough.

Looks more like a student project.
40A ? Must be joking .
Theres thousands on ebay, and chinese sites.
