Power Converter
The power converter is located below the wardrobe
behind the false panel�
The converter transforms 120-volt AC into 12-volt
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�
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�
• Using a voltmeter, check voltage output between
heavy gauge positive and negative wires coming out
of converter�
• The voltage should be within 13�8 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�
Battery Disconnect Switch
The battery disconnect is operated by using either the
main Multiplex Control Panel or by pressing the
button on the Multiplex panel located at the
entry door� You can also operate this function through
the Airstream Smart RV Control app� The disconnect
switch is used to separate the batteries from the 12-volt
distribution panel�
When the trailer is plugged into an external AC power
source the 12-volt distribution panel will receive power
from the converter and the batteries will be charged
through the converter charging system regardless of if
the battery switch is in the ON/OFF position�
If the trailer is NOT plugged into an external AC power
source and the switch is turned to OFF the batteries
are disconnected and the 12-volt fuse panel will
not receive power from the converter or batteries�
The converter will not charge the batteries when
no shoreline power is present� The OFF position
is intended for storage of the trailer or when power
conservation is desired�
The charge in the 12-volt batteries can be replenished,
depending on the tow vehicle, from the tow vehicle
alternator through the 7-way cord. This charge will flow
to the batteries regardless of the battery disconnect
switch position� Likewise, if ON or OFF, the solar panel
will still charge the batteries�
NOTE
Even with the battery disconnect switch in the
“OFF” position the LP detector will have a small
parasitic draw.
NOTE
A 24-Hr circuit provides power to the router
even when the battery disconnect is in the “Off”
position. The circuit requres 5 mA of 12-Volt Power.
Inverter
The 1,000 Watt inverter converts 12-volt electricity from
your batteries into 120-volt power� Operation of the
inverter is controlled from the main touch screen on
the first favorites page. The inverter powers the TV’s/
Entertainment devices and additional labeled 120-volt
receptacles�
NOTE
Overloading the inverter will cause an automatic
shutoff to activate. Removing the load will allow
the inverter to reset.
