HP ML 350 G6 - Power

Hi,

What is the allowable frequency range at 50 Hz for a HP Proliant ML 350 G6 server with single power supply.

We have 50 Hz supply in our country. When purchasing a UPS for this server, I have to specify the allowable output frequency range (e.g 50 Hz +/- 0.1% etc..)

Can someone please advise in this

Thanks
