Setting up the output current limit
For each model you can choose between three output currents. This setting can be useful in case the maximum out-
put current exceeds the recommended values for charging bord batteries, as might happen with AGM or Lead/Acid
batteries in general.
This function can only be activated by the DIP switch, not by an external controller (optional TD283 display or mobile
app).
Slide the DIP switches accordingly.
