Bailey Infi90 - Maximum Power Entry Panel Current Draw

MODULE POWER REQUIREMENTS
MAXIMUM POWER ENTRY PANEL CURRENT DRAW
B - 10 I-E96-508C
With N+1 redundancy
QS(N+1) = QS(N) + 1 = 4 PDS modules
Power module placement is important. For optimum cooling,
power modules should not be stacked at one end of the mod-
ule mounting unit. See Figure 3-6 for an example of how the
power modules should be positioned in the IEMMU01 and
IEMMU02 module mounting units.
NOTE:
Place a maximum of two power supply modules in any mod-
ule mounting unit, a maximum of 12 modules in any power mounting
unit.
MAXIMUM POWER ENTRY PANEL CURRENT DRAW
Add the current draw of all the power modules within the cab-
inet to the fan assembly current draw to determine the maxi-
mum current draw on the power entry panel. The current draw
of each power module is:
•
IEPDF01 module, 6.5 amps.
•
IEPDF02 module, 3.25 amps.
•
IEPDS01 module, 7.6 amps.
•
IEPDS02 module, 3.8 amps.
The current draw for each fan assembly is:
•
IEFAN03 fan assembly, 1.50 amps.
•
IEFAN05 fan assembly, 1.32 amps.
The current draw on the power entry panel should be within
its specified limit. The current draw limit on the IEPEP04
Power Entry Panel is:
•
60 amps for 24 VDC systems.
•
30 amps for 48 VDC systems.
