[Elecraft] Uninterruptible Power Supply for K3S

[Bob Nielsen]

I also live on an island and we too have several outages a year (which 
can last from seconds to days).  Most are caused by branches blown down 
by wind, hitting and breaking the power lines (it is slowly getting 
better as Puget Sound Energy has proactively been trimming trees before 
they break).  I have four UPS devices in various parts of my house. The 
shack and my home computers and DVRs are connected to 1000VA TrippLite 
UPSs I bought at Costco several years ago and these also protect against 
surges.  I don't try to operate an amp when the power goes out, but have 
run 100 watt radios barefoot for several minutes. The batteries in my 
systems probably need replacing and when I do that I will try to silence 
the darn beep that they make (I can tell when there is an outage without 
hearing that noise). I will also  look into setting up a 12V system like 
you described.

I live on an island and at stormy times of the year, we experience power losses and multiple short hits.   This combination has been quite satisfactory.
