GUIDE TO CHOOSING A DC LOAD BANK THAT FITS YOUR NEEDS

Select the DC load according to the rated voltage and rated current as the reference tables below.

Example 1: Need to check UPS with rated battery capacity 220VDC/345AH with stable discharge method C20 (20% = 69A) with end voltage volt = 182.6V and highest voltage max volt = 280V, then we choose the load as follows: Refer to table 4 – load bank 220VDC we see that the load bank VPR D220ABE100 at 180V can make constant current 82A, so C20 (69A) can be used to meet the requirements, so choose this load. is suitable.
