Functions
The transformer/rectifier has the following functions:
z
The transformer/rectifier charges the living area battery. The transformer/
rectifier charges the starter battery with a float charge only.
z
The transformer/rectifier monitors the voltage in the living area battery.
z
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.
z
The transformer/rectifier provides connections for a solar charge regulator,
an auxiliary charging unit, as well as other control and monitoring functions.
z
When the 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 transformer/rectifier only works in conjunction with a panel.
The power in the transformer/rectifier (> 18 A) is divided into charging current
and current to the appliances. The charging current is always just the portion
that is not being used by any appliances. If the current to the appliances
exceeds the current available, then the living area battery is discharged.
Position
