APPLICATION NOTES
This note will discuss DC Power sources and how they relate to 12 volt
products.
General Specifications
Our general specification for the voltage range of operation is 10 to
16 volts DC .
Voltage
The voltage of a fully charged battery ( engine not running ) is
approximately 12.5 VDC. Once a load (items being powered represent the
"load" ) is applied , the voltage will drop. How much the voltage is reduced will
depend on the following:
1. Current draw (amount of amperage) The higher the draw
greater the voltage will drop.
2. The size and length of the conductor (wire) supplying power.
Converters
Many boats incorporate convertors as a source for 12VDC when
connected to shore power (110-120 VAC).Some converters put out a very
clean DC supply where others may have a considerable amount of AC
ripple noise under maximum load.
The AC ripple noise is filtered by the boat battery when connected
into the circuit , but when the battery is
AC ripple noise can create major problems for audio products. Noise
may result and the line fuse may fail
Ignition systems
Unwanted noise generated from ignition systems used to be a
problem. However, with more sophisticated filtering circuits designed into
audio/video products, these problems are not as wide spread
Changes in wire harnessing also has contributed to the decline of
application problems. Use the same ground point for all related products. This
will greatly reduce the potential for unwanted noise.
Your MS160 radio is designed to control an optional 10 -
Disc CD changer ( Model ACC56M ) . If you are interested in
