DC Power Distribution:
Not all shacks run DC exclusively. Some have no DC at all,
some are totally DC, but most are partial DC power.
Many hams have rigs that are meant for mobile use and are
used as base units. Many HF rigs run on DC only and the
additional cost of a power supply is not within the wallet of
most. They resort to batteries and chargers. Some enjoy the
advantage of power on request from a battery bank, powered by
a large power supply and several batteries. No commercial
power, no problem.
Others prefer commercial supplies or many commercial
supplies; one for each radio. Some even enjoy the use of an
Uninterupted Power Supply (UPS).
Regardless of what you use, there are some DC distribution
ideas I would like to convey to the readers.
------------
DC POWER PANEL
You may have to either distribute your DC power from one source
or recharge your several DC sources from one commercial source or
a combination of the two.
Here's an example of a simple DC power panel in use here:
All rigs are DC powered;
o Ten-Tec Closet Kilowatt
o Kenwood TS-430S
o Kenwood TR-751A
o Kenwood TM-421A
The battery bank consists of four deep cycle batteries rated at
115 AH each. Power supply is a Pyramid Phase II 50A.

The power and ground bus run like this to the power supply:
ground bus-------------------------P/S ground
*Batt 1--------SW1-----------------|---P/S positive
*Batt 2--------SW2-----------------|
*Batt 3--------SW3-----------------|
*Batt 4--------SW4-----------------|
It's farly simple system that allows the rigs to be operated
with or without charging in line.
