but with voltage input range 100-240v
not 200-240
if not present what is the biggest server psu with input 100-240
You are going to have a hard time finding one. Power(watts)=Volts*Amps so... 2400 watts divided by 120v would be 20 amps. Most household electrical circuits on 120v are on 15 amp breakers. You should really only use 80% of a circuit, so the maximum you should put on a 15 amp breaker would be 1440 watts at 120 volts.
This is why 2400 watt PSUs will only work on 220-240V. The wiring is a much lower gauge, which means it can handle more current (amperage), and thus can handle the higher wattage. Plus 240V circuits are usually on larger breakers to accommodate the larger wattage and amperage.

thanx for the explanation
but what 'll happen if i ran this psu on 180 volt ?
the problem is where i live we have public problem in voltage normal voltage is 170-200 volt varying all over the day according to the load
this is the cause to look for a psu 100-240
It will not power on at 180V. The minimum is 200V
