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.
Fuse panel may have 6, 9, 12,15 or 20 fuse positions, depending on
output size of your converter.
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 installed in a different location (not mounted into
distribution box).
The function of a converter takes 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 most interior lights. The
floor plan and size of coach indicate the output size.
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.
