9.5 Transformer/rectifier EBL 109 (Autark Package)
Functions The transformer/rectifier has the following functions:
z The transformer/rectifier charges the living area battery.
z The transformer/rectifier distributes the current to the 12 V circuits and secures
them.
z The transformer/rectifier contains connections for a solar charge regulator as
well as other control and monitoring functions.
z The transformer/rectifier separates the starter battery of the towing vehicle
electrically from the living area battery of the caravan if there is an electric con-
nection between the towing vehicle and the caravan and if the vehicle engine
is turned off. In this way the 12 V appliances of the caravan cannot discharge the
starter battery of the towing vehicle.
z The transformer/rectifier distributes the current to the 12 V sockets. Devices
with a maximum of 10 A can be connected to the sockets.
The transformer/rectifier only works in conjunction with a panel.
When the transformer/rectifier is subject to a heavy load, the fitted charger module
reduces the charging current. This protects the charging device against over-
heating. The transformer/rectifier is subject to a heavy load when e.g. an empty
living area battery is charged, additional electrical appliances are turned on and the
ambient temperatures are high.
Z Do not cover the ventilation slots. Danger of overheating!
