MAGMA
28 Appendix B DC Power Information
Notes:
1. This table applies to CB1H/CB1F systems only. Do NOT use
for CB232 systems.
2. Calculations assume continuous operation at maximum
designed load.
3. Margin of safety used is 10%.
4. Determine the number of Desired Continuous Operating Hours
you would like to operate before recharging. (Column 1)
5. Determine the Battery Output Voltage of the battery you would
like to use. (Column 2-4)
6. Read the cell value in the table for the Amp Hours required.
Use this number when choosing a battery (or set of batteries).
7. If you required more than 8 hours- use multiples of a lesser
number of hours.
Examples:
If you want 5 hours of continuous operati
on with a 14.4VDC battery set:
Locate row 5 in Column 1 of the table above, read across the row to the
14.4VDC Column, you will find that you will need a battery (or set of
batteries) with a total power rating of about 17 Amp Hours.
If you want 10 hours
of continuous operation with this same battery set
(at 14.4VDC), would need a total power rating of about 34 Amp Hours
(2 x 17 from the above example).
For Batteries Rated in Watt Hours:
If the vendor rates the batteries in Watt Hours, then simply multiply the
number of desired hours of use by 45 to get total Watt Hours
rating
requirement.
If you want to run the CB1 for up to 4 hours: 4 hours x 45 Watts = 180
Watt Hours
is required for the selected battery set.
