[Elecraft] Uninterruptible Power Supply for K3S

[Richard Fjeld]

John,
I haven't read all the replies yet. I'm sure you will get a variety of 
responses, such as mine.

About 40 years ago when color TV's were more expensive, my neighborhood 
got a momentary hit in the power, and it came back with a voltage spike 
that took out too many TV's to count.  To prevent that from happening to 
my ham gear, I made a box with multiple outlets all switched by one 
relay that locks up through it's own contacts.  I have momentary push 
button switches to operate, or release, the relay.  Should the power 
take a momentary hit, the relay drops and opens the AC line to my 
equipment.  If the power comes back with a voltage spike, my equipment 
doesn't see it. (This may result in a discussion about MOV's)  I have a 
100 watt station.

I prefer to float a battery across my 12 volt line to allow me to 
properly shut down my equipment should the power go out.  I have had 
several qso's with people who use 12 V battery power exclusively. Some 
live where there is no power grid.

Also, I have a UPS that powers a lamp at my operating position so that I 
can see to power down my equipment.  I hope to eliminate this with a 
good 12 Volt LED lamp when I find one.

Dick, n0ce
