DC Power Supply for DAE D3122F

Team, 

Do any of you have a 1100W DC power supply for a DAE D3122F connected to a Unity 300F.
I need to buy a pair of power supplies but the Dell EMC part number is nowhere to be found. The Dell EMC part number is 071-000-605-02.  The manufacturer is ACBEL and if anyone has such a power supply, I would like to share with me the ACBEL manufacturer's part number as that number is easier to find in the market.
