(While I'm at it...)

 

Is it a good idea / bad idea / waste of money to plug the big ol'
modular into a PC-type Uninterruptible Power Supply? You know, one of
those heavy APC 1000VA Smart-Ups-type units?

 

With those units, you are warned against plugging laser printers into
them because the power spikes so much when they are first turned on.
Would a modular present a similar problem? (I'm talking a lot of
modules...)

 

Thanks in advance for any opinions.

You are better off with a Sola or Topaz isolation transformer.

UPSs are NOT forgiving with power-up surges. I suspect a large (40+) MOTM
system has such a surge.

To Paul (or anyone else):

Can you comment on the differences between battery backup systems and
isolation transformers?  I need a power device that will protect the
modular.  Power-up surges may not be a problem...I have multiple power
supplies that I turn on sequentially (manually).  Why would I use an
isolation tranformer rather than a battery backup UPS?  If UPS, is a
UPS with a sine wave output necessary or desirable?  Are there better
UPSs for what I want to do?  Finally, can you recommend some makes (or
models)?

Thanks!
Hans

An isolation transformer offers isolation from the AC line.  A UPS or
battery backup provides power for a short time after the power goes
go out.  They are two completely different things, neither of which
you need for MOTM.

I use Tripplite Isobars for general use.  I have them all over the
house.  They provide filtering and surge protection.  I also have two
Tripplite two LC-2400 20A line conditioners for studio use.

I have a UPS, but I don't use it since the computer I use at home is
a laptop.  It has a battery of its own, so it still works if the
power goes out, allowing me to save whatever I'm doing.
