Dimensioning The Upstream Power Supply - Bicker Elektronik UPSI-IP-1 Series User Manual

7 Dimensioning the upstream power supply

Pay attention that the source is correctly dimensioned and supplies enough current to
ensure the charging process and the function of the application. The UPSI reduces its
charging current depending on the load. However, care must be taken to ensure that
the battery pack can be charged even at maximum load. This results in the following
minimum requirements for the PSU source depending on the load:
