F5 Dimensioning the upstream power supply
Ensure that the upstream power supply is correctly dimensioned to guarantee the charging process of the
batteries and the correct functioning of the application. The input has to be supplied from a SELV or PELV
power supply. In order to operate the UPSI-2412 with complete functionality, the upstream power supply has
to provide at least 24 V / 20 A and use
no
constant current function.
If less load than the maximum load is required at the output, the voltage supply can be dimensioned according
to the table below (column 3).
