Multiple isolated outputs
The Blue Smart IP22 Charger 3 output models include an integrated FET battery isolator and multiple isolated outputs.
Multiple isolated outputs make it possible for a single charger to charge multiple individual batteries that are at a different voltage/SOC level without current flow between the batteries, and with the charge current intrinsically distributed between all batteries depending on their voltage/SOC level and capacity.
The 3 output charger models can supply the full rated output current from all 3 outputs; however the combined current of all outputs is limited to the full rated output current.
Notice
The multiple isolated outputs are not regulated individually, one charge algorithm (charge cycle and charge voltage) is applied to all outputs; accordingly all batteries will need to be compatible with the common charge algorithm (typically the same chemistry type).
