DC DISTRIBUTION
PANEL AT VK6RAV REPEATER
New
12VDC distribution panel - May 2024
Over the years the
VK6RAV repeater has had many ad hoc additions and modification that
had left the equipment installations looking quiet confusing and
lacking any standard. Central to this chaos was the 12VDC distribution
panel that lack consistency and including non-adherence to basic
wiring colour code.
The new 12VDC
distribution panel was constructed around some basic principles that
include;
-
That as much as
possible all wiring would be behind the panel including leads
connecting equipment to the panel.
-
All equipment
circuit would have an individual protection fuse and that the
fuses would be restricted to two current ratings, 5A for minor
equipment and 20A for higher load equipment such as the repeater.
-
Positive wires
may be any obvious colour other than BLACK or GREEN. RED is
preferred.
-
Negative wires
are to be BLACK or sleeved with BLACK heat shrink tube or similar.
-
Fuses are
Standard Blade Fuses (ATC/ATO)
-
12VDC supplies
are made available for lighting, mains voltage inverter and other
12v type equipment via a 50A Anderson connector and 30A mini
Anderson connectors.
