6.3.3 Power Save
The Supervisor can improve operational efficiency when conditions warrant by running only the neces-
sary number of rectifiers. The remote shutdown setting (enable or disable) affects correct operation of the
Power Save feature. See also 2.6 for more details.
6.3.3.1 Enable
The Supervisor can control the CXC Power Save feature.
6.3.3.2 Redundant Rectifiers
The Supervisor can specify the number of extra rectifiers to turn on.
6.3.3.3 Max (Maximum) Power Usage
The Supervisor can specify the percentage (of maximum power usage) per rectifier module used in the
computation of the Power Save feature. This works to avoid rectifiers operating continuously at greater
than the set limit (i.e. 95%) and going into current limit frequently due to load surges or power limit condi-
tions; such as, low line voltage or high temperature.
6.3.3.4 Phase Mapping
The user can assign or map a rectifier per input signal for individual phase voltage readings:
Assign/map a rectifier per Phase R, S, and T
(radio buttons) for the respective signal
Tap Locate and the LEDs of the selected rectifier
will flash to enable the user to determine the phase
connection
