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 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 in to 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.
Converter Operation
The 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(ies), 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 of the power converter
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 the 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.
Converter Cooling System
The converters electronic fan cooling system is the key
to long life and trouble-free operation� The fan is never
on more than required to cool electronic components in
the converter� You may never hear the fan operate�
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�
