Hi,

Well, = years of getting their quality up, CyberPower has my attention.  =

More than anything you don't want a simulated sine wave.=   You want a real sine wave.

You want direct draw of= f the batteries at all time.  An AC -> DC switch is "Bad".  Th= e 'burst' can cause life-loss or total failure of components.

I've had my server on a 1500A unit for over 5 years and did a recent d= rain and recharge.  It came right back to telling me I had 22 minutes = of reserve power.  (Which is how long it told me on discharge and I st= opped it 21 minutes.

=
So, just upgraded my server.  G= ot the latest unit again for my server/Desktop and I passed the old UPS ont= o the son's workstation.

Everything continues to work, bu= t I'll take a closer look in 2 years.

Hello:

    I have an older APC UPS (BackUPS = RS 1500) that after years of
excellent service _m= ay_ need to be replaced.
    Is th= ere a particular brand - or even model - that folks would
recommend for a medium-to-heavy home office environment?  (Th= is isn't
the only UPS; it's just the only one cau= siong problems right now.)
    Bud= get is not unlimited, so I'm not looking for anything fancy;
just something that will (with replacement batteries) just do i= ts job
for the next 15+ years.
    And - of course - works with software running o= n FreeGSD.  (I use
apcupsd, and have seen nu= t used elsewhere.)
