Converter Operation

The electronic power converter is designed to supply
the nominal 12-volt-filtered DC power for all 12-volt-
operated devices encountered in RV service� Although
the converter is an excellent battery charger, the
converter does not require a battery to be connected to
it for proper operation�
NOTE
When installing a battery (s), always observe
polarity. Connecting a battery in reverse polarity
will blow the power converter main fuses located
on the 12-volt DC distribution fuse block.

120-Volt AC Panel Board

The AC panel board section contains the 120 VAC
branch circuit breakers for your RV� One of the
breakers controls the 120-volt power to the 12-volt
converter section� This breaker may also control
another branch circuit� Check the label next to each
breaker for what each branch circuit breaker controls�
The 120-volt circuits may be turned on by setting their
breaker handle up, to the ON position, or off by setting
the handle down, to the OFF position� To reset the
tripped breaker, move handle to OFF then ON�
The system incorporates GFCI breakers that
implement an auto self-test functionality� When turned
off, these breakers require external AC power to be
present, or the AC inverter enabled, before they can
be turned back on� If AC power is present from one of
these two sources, and the breaker refuses to stay on
consult an electrician or certified RV technician.

Fuses and Breakers

Breakers

The distribution panel was designed to use a 30 AMP
120Volt main breaker with branch circuits� Double
breakers may be used for the branch circuits� Should
a breaker become faulty replace with the same type
breaker only� Use only approved circuit breakers and
12V fuses�
NOTE
When replacing circuit breakers replace with the
same type and rating as the original.

12 VDC Fuses

Each 12 VDC circuit in the distribution panel was
designed for a maximum of a 20 amp automotive
style fuse� Should one need to be replaced, be sure
to replace it with the same type and Amp rating as
originally supplied by Airstream� Replacing it with either
a higher or lower Amp fuse could result in the panel not
functioning properly�

REVERSE Polarity Fuses

The power converter is equipped with reverse polarity
fuses, Should these fuses "blow" either during the
manufacturing process or while connecting the battery,
replace with the same type and rating fuse as originally
provided with the equipment�
The power converter is not weather resistant nor
designed for installation in wet locations� The power
converter must be protected from direct contact with
water�

Automatic Micro-Controller Operation

The power converters 3-stage switch mode is fully
automatic� The converter senses which mode it needs
to be in by checking the condition of the battery� The
three modes include:
Absorption Mode: During this mode the converter
output is in the 13�6 VDC range� This is the mode
that the converter will function at normally� This mode
provides the 12 VDC and the current required by the
trailer�
Bulk Mode: In this mode, the output voltage of the
converter will switch to 14�4 VDC range for a maximum
of four hours� If the converter cycles between
"Absorption and Bulk modes", there could be a shorted
battery cell or other issues�
Float Mode: If the trailer has not been used for a
period of time and the shore power has been left
plugged in, the converter will automatically go into
float mode with a voltage of 13.2. When the converter
senses a demand, by turning on lights, the converter
automatically returns to absorption mode�
