Power Center; 12-Volt Power Circuits - Airstream FLYING CLOUD 2024 Owner's Manual

Interior

Power Center

The power center is installed below the refrigerator,
wardrobe, pantry, or bed, depending on the model�
Open the decorative door for access to 12-volt fuses
and 120- volt breakers�
The power center's converter transforms 120-volt
alternating current (AC) into 12-volt direct current
(DC)�The converter/charging system is the interior low
voltage electrical system that enables you to use the
interior lights, fans, pumps, and 12-volt appliances,
whether operating on self-contained battery power or
120-volt city power� The 12-volt light bulbs give off the
same light as regular household bulbs, so that when
operating on self-contained battery power, everything
works normally except the 120-volt convenience
outlets and 120-volt appliances� The converter system
is designed to maintain constant output voltages
regardless of the variances that occur in city power
systems�
WARNING
The power center is a centralized power
switching, fusing, and distribution center. The
potential for lethal electrical shock is present
in this box. Inadvertent shorts at this box could
result in damage and/or injury. All servicing of
this box should be done by a qualified Service
Technician.
WARNING
Disconnect/De-energize all main power service,
shore power, generator power, and inverter power
prior to servicing the breaker panel.
The converter is energized only when the trailer is
hooked up to external AC power�
To test the converter, observe the following:
• Confirm 120-volt power is going into converter.
• Disconnect the 12+ wire from the master switch�
5-10
• Using a voltmeter, check voltage output between
heavy gauge positive and negative wires coming out
of converter�
• The voltage must be within 13�6 and 14�0 volts� (The
meter of the tester should be calibrated periodically�)
• If converter is not within these voltages, have it
serviced by a qualified technician or replace it.
One of these wires is not spliced onto a wire of the
same color� It is the backup wire that is yellow in the
cable and black in the harness�
A label on the inside of the converter door lists the
circuits and what each fuse powers�

12-Volt Power Circuits

The current in the converter system is 12 volts direct
current (12 VDC) negative grounded� Power sources
that supply 12 VDC current to the system are as
follows:
• Main charge line from tow vehicle
• Trailer batteries
• Converter
The power sources listed above are all electrically
connected to the 12-volt distribution fuse panel that
distributes current to interior branch circuits� The
circuits provide power to operate all 12-volt DC lights,
pumps, motors, and appliances�
The power converter is a solid-state electronic power
supply and is maintenance-free. It is so self-sufficient
and quiet that you will probably not know it is working
except for the fact that your batteries are always
charged, and your 12-volt lights and appliances always
work�
If any 12-volt appliance fails to operate, first check
your 12-volt distribution fuse block, located behind the
decorative front door in the front right-hand corner of
the converter and inspect all fuses� If a fuse is opened
or blown, replace it with the same size fuse (never
install a larger fuse)� If the fuse opens again, have an
electrician or certified RV technician locate the circuit
trouble� Replace blown fuses only with the same type
and amperage size previously used�
If the power converter is not working, first confirm
the RV supply or shoreline cord is plugged into a live
circuit� Then check all the 120-volt breakers in your
RV distribution panel to make sure they are on� If
the breaker is tripped, follow the instructions to reset
the breakers� If the breaker trips again, consult an
electrician or certified RV technician.
