22.4. N+1 REDUNDANCY, EXAMPLE WITH 20A
N+1 Redundancy with 20A requires three 10A power supplies and two YR2.DIODE decoupling modules.
Please note:
The DC-ok signal on the DIMENSION Q-Series will only work properly if the adjusted output voltage of each power
supply will be reached after turning-on the input power. A power supply operating in current limiting mode will result
in a DC-fail condition. Read notes in the individual power supply datasheets.
