The table below allows you to select the most appropriate 48VDC power system for a 2-hour back-up time. All that is required is an understanding of the continuous load required for the application. Simply identify the load from the first column which is equal to or higher than your actual load requirement, and click on the system type in the second column. For example, a load requirement of 2700-Watts, would require a selection of a 3000W load, which corresponds to a CX48 Type 9 system.

Load (Watts)	2 Hours (Autonomy of System)
800	CX 48 Type 1
1000	CX 48 Type 2
1100	CX 48 Type 2
1450	CX 48 Type 2
1700	CX 48 Type 3
2000	CX 48 Type 5
2500	CX 48 Type 6
3000	CX 48 Type 9
3450	CX 48 Type 9
4000	CX 48 Type 12
4300	CX 48 Type 12
4500	CX 48 Type 12
5200	CX 48 Type 12
6000	CX 48 Type 15
7000	CX 48 Type 15
7900	CX 48 Type 17
10500	CX 48 Type 20
