# 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.

## Table 1 – 24VDC load bank current specification (max 30V)

Note:
– 24V load used to test DC voltage from 8V 30V (or lower to 1V) according to the current parameter table as above
– 24VDC voltage is the nominal voltage to identify a power source
– The rated current of the load bank is the current calculated at the rated voltage of 24V .
