Bailey Infi 90 - For Systems Using both IEPAS02 and IEPAF02 Modules

MODULE POWER REQUIREMENTS
SIZING THE MODULAR POWER SYSTEM
I-E96-506B1 B - 7
Substitute these values into the equations and solve for Q.
QS
= Largest of Q1, Q2, Q3, Q4 and Q5 = 2.038
Number of power modules required for system.
QS
= 2.038
Round the value of QS to the next highest integer.
QS
= 3 IEPAS02 modules
With N+1 redundancy where N = QS.
QS
(N+1)
= 3 + 1 = 4 IEPAS02 modules
For Systems Using Both IEPAS02 and IEPAF02 Modules
Let:
A
Total 5 VDC current requirements for system cabinet.
B
Total 24 VDC current requirements for associated I/O.
C
Total +15 VDC current requirements for system cabi-
net.
D
Total -15 VDC current requirements for system cabinet.
Q1
Number of IEPAS02 power modules needed to meet 5 V
current requirements.
Q2
Number of IEPAS02 power modules needed to meet 24
V current requirements.
Q3
Number of IEPAS02 power modules needed to meet +15
V current requirements.
