Yes they are several times
the cost of regular deep cycle lead acid, but they will run for 15-20
years, so in balances out
over time.

You can pay up front, or you can spend your money on gasoline, tires,
and wear and tear getting
to/from your site.?? For those of us that have to get to mountain tops,
it pays to do it well the first
time.?? And just like generators, remember to look closely at the specs
for your power supply if you
are operating at Altitude, most specs are only to 10K or lower.

Very nice supplies, indeed Chuck, actually almost mind boggling to get all that power out of such a small area 1U rack. I was just concerned about the reliability of what is probably a very small diameter cooling fan, so I looked up the warranty and it was 2 yrs on the supply. I had surmised that a small fan running at a higher speed would be less reliable with time. That did not seem to be true up on a quick check with Digi-Key on small high rpm (40mm diameter) vs larger slower running (80mm) fans of the same manufacturer, had the same lifetime. The only longevity difference was in the bearing type. Sleeve bearing fans had 40 degree C continuous full speed lifetime of 35,000 hrs (4 yrs) - Double ball bearing fans 50,000 hrs (5.7 yrs), and Vapo Bearing fans 70,000 hrs (8 yrs).

I wonder if you know if the fan on the ICT units run full speed all the time, or are temperature speed controlled, giving longer fan lifetime?
