PE is the abbreviation for Protective Earth and has the same meaning as the symbol
This document uses the term "earth" which is the same as the U.S. term "ground".
To be defined, value or description will follow later.
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)
A figure with the unit (Vdc) at the end is a momentary figure without any additional
tolerances included.
A key word indicating flexibility of choice with no implied preference
A key word indicating a mandatory requirement
A key word indicating flexibility of choice with a strongly preferred implementation
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 2.5A power supplies are needed to
achieve a 2.5A redundant system.
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 10A redundant system, five 2.5A power supplies are needed in
a N+1 redundant system.
