DC 24V
A figure displayed with the AC or DC before the value represents a nominal voltage with
standard tolerances (usually ±15%) included.
E.g.: DC 12V describes a 12V battery disregarding whether it is full (13.7V) or flat (10V)
24Vdc
A figure with the unit (Vdc) at the end is a momentary figure without any additional
tolerances included.

1+1 Redundancy
Use of two identical power supplies in parallel to provide continued operation following most
failures in a single power supply. The two power supply outputs should be isolated from each
other by utilizing diodes or other switching arrangements. E.g. two 10A power supplies are
needed to achieve a 10A redundant
system.
N+1 Redundancy
Use of three or more identical power
supplies in parallel to provide
continued operation following most
failures in a single power supply. All
power supply outputs should be
isolated from each other by utilizing
diodes or other switching
arrangements.
E.g.: To achieve a 30A redundant
system, four 10A power supplies are
needed in a N+1 redundant system.
