Thanks in advance, everyone. I’m new to the group, and here’s my question:

I need to install a new battery charger in my campervan’s electrical system, replacing the current one, so that it can handle lithium batteries.

The campervan has a control unit that displays a symbol when 230 V AC mains power is present. The system is controlled by an auxiliary input that requires a +12 V signal when this power is present.

I was wondering whether it would be possible to take this +12 V signal directly from the battery charger.

Since the main output connectors are connected to the ArSlicii Power-Link 2 TTK unit, would the 220 V presence symbol be activated correctly?

Thanks to anyone who can help
