SC-2345/2350 Carrier User Manual
SC-2350 Carrier
For the SCC-PWR01 to supply enough power for your SCC configuration
in the SC-2350 carrier, the following three conditions must be true:
P
A
≤
P
AMax
and
P
D
≤
P
DMax
and
P
A
/0.62 +
P
D
+ 0.53 W
≤
P
S
where
P
A
is the total analog power required by your SCC configuration,
in watts;
P
AMax
is the maximum analog power available in watts, from
Table C-3;
P
D
is the total digital power required by your SCC configuration,
in watts;
P
DMax
is the maximum digital power available in watts, from
Table C-3; and
P
S
is the rating of the power supply in watts.
Calculating the Power Available from the SCC-PWR02
The following section discusses the conditions which must be met for the
SCC-PWR02 to supply enough power for the SCC configuration on the
SC carriers.
