The transformer/rectifier has the following functions:
The transformer/rectifier charges the living area battery. The trans-
former/rectifier charges the starter battery with a float charge only.
The transformer/rectifier monitors the voltage in the living area battery.
The transformer/rectifier distributes the current to the 12 V circuits and
secures them. Devices with a maximum of 10 A can be connected to the
sockets.
The transformer/rectifier provides connections for a solar charge regula-
tor, an auxiliary charging unit, as well as other control and monitoring
functions.
When the vehicle engine is turned off, the transformer/rectifier separates
the starter battery electrically from the living area battery. This prevents
the 12 V living area appliances from discharging the starter battery.
The battery cut-off switch in the transformer/rectifier separates all the
appliances from the living area battery.
The transformer/rectifier only works in conjunction with a panel.
The current available at the transformer/rectifier (18 A maximum) is divided
into charging current and current for the appliances. The charging current is
always just the portion that is not being used by any appliances. If the cur-
rent to the appliances exceeds the current available, then the living area bat-
tery is discharged.
The transformer/rectifier is installed in the double floor and accessible via a
floor trap in the living area.
