MLY-Series
DC12-48V, 10A, DUAL REDUNDANCY MODULE
18.4. EXAMPLE: N+1 REDUNDANCY
N+1 Redundancy up to 6.3A requires four ML50.100 power supplies (each 2.1A output current) and two MLY02.100
redundancy modules.

Note: Use separate mains systems for each power supply whenever it is possible
18.5. EXAMPLE: BATTERY BACK-UP
A battery back-up requires one power supply and one MLY02.100 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 charger (battery). Use a fuse between battery and MLY02.100!
