Thanks;
I assume the APC1500 is stepped sinewave? Also good idea about the cable
box. Mine is a DVR with a harddrive.
I should clarify that these are not brown outs but are >repeated blackouts
as the power utility trys and fails to >auotomatically reclose its breakers.
This results in an >OFF/ON/OFF/ON/OFF cycle.
sometimes blackouts begin with a brownout.Here in Crete, half of the island
was left without power, when on one of the 3 main power stations, outside of
Iraklion, was a short circuit in one of the 150 kV insulators, but the other
half of the island remained "live".The infamous blackout of Athens, just a
few months before the olympic games, happened when several units were lost
of tripping, the worst one 300 MW just outside of Athens.When they tried to
bring it back, it tripped again because of some steam problem, and just a
couple of seconds before the 400 kV breakers opened, separating the south
grid from the north grid, the voltage at the busbars had fallen down to 107
kV (nominal:150 kV).IMHO you should do nothing, just when the power is out
be sure that you have turned everything off (maybe with a switched power
strip) and when you are sure power is really back, turn everything back on.

Hi;
I have just bought a new Sony Bravia 46S2010 LCD TV. The operations
manual warns against pulling the AC plug without first turning off the
TV. - No problem, I would like to run the TV and my Pioneer 300 disc
PD-F1007 Jukebox CD changer* from a UPS
The UPS I am considering would be something like an APC Back-UPS 650,
which are plentiful, easy to repair but have a stepped sinewave output.
Can anyone tell me if there would be any reliability issues in running
this setup? I know that there might be an AC hum issue with the sound
system due to switching transients. I don't intend to back up my audio
amplifier. I only want the TV and CD changer to ride out the numerous
brownouts we get in Florida.
(*The Pioneer must be on standby to retain memory and turns back on from
standby on power interruptions).
Been running a Panasonic 51" rear projection on an APC 1500 for a few
years. Also run my DirecTV DVR on it. Did this after getting fed up with
power interruptions that have since been fixed. I don't notice any
problems with my equipment.
