19.5. Example: Battery Back-up
A battery back-up with 10A requires one 10A power supply and one 1606-XLERED redundancy module.
Please note:
Set output voltage of power supply to 26.5Vdc minimum to ensure that the load current is delivered from the power
supply and not from the charger (battery). Use a fuse between the battery and the 1606-XLERED module!
