vehicle battery and/or auxiliary battery through the seven way
connecter and wire attached to the tow vehicle. Following are
explanations of various items.
Converter
The heart of your 12 volt DC system is enclosed inside of the load
center, including 12V fuse panel, 120V breaker panel and converter.
The function of a convertor receives 120 volt AC Power and
transforms this energy into 12 volt DC Power as used in your coach.
12 volt DC supplies power for some appliances and interior lights.
The floor plan and size of coach indicate output size. Fuse panel will
have numerous fuse positions, depending on output size of your
converter and requirements.
All converters have solid state electronic components internally to
produce “clean” 12V DC power.
This load center will have a brown plastic front with a small door to
access fuses and breakers.
Some models have fuses and breakers in a distribution box, with
converter free standing, installed in a different location (not
mounted into distribution box). This is the 50 amp option.
When the converter receives 120 AC power, it transfers power into
12-volt DC without any manual switches. The converter also
charges the auxiliary battery( s) when installed on the coach and
attached to 120-volt AC power. The third function of a converter is
to send 12-volt power to the fuse panel and throughout the coach.
Each converter has a “built-in” fan which operates through a load
sensor control or temperature sensor. As more current is drawn, fan
will speed up, run faster, or slow down, based on amp draw and/or
temperature. Should the fan not run at all, the converter may
overheat and will cut-out and/or stop.
Auxiliary Battery (Optional on Some Units)
All travel trailers and fifth wheels are pre-built to accept a battery.
Batteries are not standard equipment, or offered as an option on
units. They can be purchased from your dealer or battery store.
Recommended batteries are of deep-cycle type as you need longer,
slow consuming power rather than cold-cranking power. A battery is
