Altronix AL1024ULX - Battery Size Calculation; Battery Capacity Calculation Worksheet

AL1024ULX Series - 7 -
Battery Size Calculation Worksheet:
A. AL1024ULX series internal current consumption (stand-by) __________________ 0.05 A
B. Load current consumption (stand-by) __________________ A
C. Stand-by time required (hours) __________________ H
D. Battery capacity required for stand-by (A+B)*C __________________ AH
E. AL1024ULX series internal power consumption (Alarm) __________________ 0.05 A
F. Load current consumption (Alarm) __________________ A
G. Alarm duration (Hours; 15 Min. = 0.25 Hour) (Alarm) __________________ H
H. Battery capacity required for Alarm (E+F)*G __________________ AH
I. Total calculated battery capacity D+H __________________ AH
J. Battery capacity required I*1.8 (safety factor) __________________ AH
Note: AL1024ULX series power supply is designed to work with batteries up to 65AH.
Please note: line [I] must not exceeds 36AH.
You have to reduce either stand-by current consumption or stand-by time in order to comply with requirement.
To determine actual battery size please round line [J] to the nearest larger standard battery size
(e.g. 3.5 AH = 4.0 AH).
