[Elecraft] [K3] UPS for K3

[Jim N7US]

Is it overkill to power my Astron RS-35 power supply that runs my K3 from a
UPS?  I am looking at a CyberPower CST1300AL from Costco
(http://tinyurl.com/pajlsav) .  It produces a "modified sine wave" when the
primary power has been lost, which is true of most UPS models.

I'm usually home so the plan is to turn the K3 off with its power switch in
the event of a power failure.

Looking at
http://www.cyberpowersystems.com/support/faqs/topologysinewave.html my
conclusion is that type of UPS is adequate for an Astron supply powering the
K3, a computer, and accessories, but I'm no engineer.
