PowerEdge R550 swapping DC PSU to AC

Hello, 

We have R550 with dual CPU (Intel Xeon Gold 5318Y ) and it came with dual PSU but it is DC (1100W FR)

We need to swap the PSU from DC to AC and we are not sure which part number goes with it. 

This is PN for the DC PSU: 

0FW1R - 450-AKMN : Dual, Hot-plug, Redundant Powe r Supply (1+1), 1100W -48VDC ( CAUTION Only Works with DC Pow er Input)
