I have a linux cluster and need to purchase a UPS system.
The total expected current consumption will be 240 amps. At 120 V this
would require a 30 kVA UPS system.
However, I see that 30 kVA systems have a limitation for the input
current. For example, this 30 kVA system
(http://www.provantage.com/tripp-lite-su30k3-3xr5~7TRPL1Q9.htm) allows
only 90 amps as input
current. I am a bit confused here, and I need some advice on what UPS
system I should look for.
