The CSV 409 A caravan charging system is the central power supply unit for
all 12 V consumers connected to the caravan’s electrical system. It is nor-
mally fitted inside a cabinet or a stowage space and can be accessed from
the front to change a fuse.
The caravan charging system has been designed solely for connecting up to
a 12 V onboard supply.
Connected units can be supplied from the caravan battery or the towing
vehicle’s battery if a mains supply is not available.
Since the device provides a hum-free, stabilised output voltage, it is also
possible to connect and supply power to sensitive consumers (e.g. transistor
lamps or radios).
The CSV 409 A caravan charging system consists of:
F
A charging module for recharging all of the connected batteries
F
The complete 12 V distribution system
F
