Power protection question
Power protection question
(OP)
Ok likely an easy question.I am looking to power my server room like this:
60a 3phase > apc 15kva ups > 3phase PDU1
60a 3phase > 3phase PDU2
Current load aprox 7500w
I am parinoid about the power going to PDU2 as it would come straight off the mains. Is there a surge supressor/filter or something that I can put in the middle to let me sleep better at night knowing my servers arnt going to get blown up by a random spike on the mains or my generator when it kicks in? (Unfortunately, I dont think my pdus have a surge supressors.)

I do not wish to put a UPS on PDU2 because it costs more to aquire, maintain, and sucks 5% efficency off the top, not to mention another 5k btu of heat.
I am looking for a surge suppressor that will mount in line from the mains or a PDU that has one integrated but I seem to be having a hard time finding anything.

they're about $2900 each, so getting 7500VA of coverage will cost you nearly $9000. Are you sure that's a saving over going with UPS coverage on both ?
How about a UPS with dual feeds, so it can run off either of your PDU's - same idea as redundant power supplies in a server, just further back up the power chain ??

Mains-> Transfer switch and generator-> Main Breaker pannel. Its 125kva and backs up the office. Takes 1-2 seconds to kick in.
I had considered wiring both to the ups, and then having a straight wall outlet that I can connect one to as a very manual way of bypassing the UPS. (Should it have a major issue or need maintinance/replacing) And this is what I will do should I not find something that will work.
I know the protection isn't perfect, but the odds of a power supply going out on the ups psu and the power going out before I can either replace/swap the psu or make sure the working one is on the ups are just so low that I wont lose any sleep over it.
I was thinking something like: http:/
Might be sufficient.

The Power Conditioners I pointed to earlier also handle voltage fluctuations (over and under) as well as suppressing surges. That can also be a nice feature if power becomes 'iffy' without actually failing. You know your local environment best.
