[LinuxUsers] Sine wave vs shaped square wave

[Jeff Lasman]

I run my office on four UPS units; all APC smart-UPS with full sine-wave 
output.

The one running my network failed today, during one of those 
thunderstorms that came through.

I can get it rebuilt, but not by tomorrow (I'm temporarily running my 
network on my main UPS, which is large enough to handle the load, but 
not for long in a power failure).

So I'm looking at replacing it.

Question: years ago the common knowledge was to use sine-wave power 
because it was better for the systems.

The last time I studied this was about the turn of the century; I fully 
realize that things may have changed.

So today I'm not sure. What do you think?  Any experience?

Thanks for any input.

Jeff
