[GCARC] Power supply

[Christopher Prioli AD2CS]

Hi Todd...

The Icom IC-2300H is a single-band 2-meter radio with a 65W maximum power
output.  According to its spec sheet, it draws 11 amperes at maximum output
power.  With that in mind, and *if you are only concerned with powering
this particular radio,* a 30 amp power supply is overkill.

The rule of thumb that I suggest, and I follow myself, is to provide a
power supply capable of 150% of the maximum draw expected.  THis allows the
power supply to meet the current demand with a comfortable margin, which
allows the power supply toi run cooler and last longer.  Thus, for the
IC-23600H, a 20-amp supply will be a good fit.

If you are considering powering additional or other radios in the future,
then I would suggest going the other way, and getting a supply that can
meet considerable future needs,  There is a good 50-amp supply available
that I like.  I use it myself, and I put one on the test and repair bench
at the clubhouse.  It is the TekPower TP-50SW, and it is available from
many sources, including Amazon.  This PSU has some unique and attractive
features, including a noise offset adjustment.

The best supply is the one that meets your needs at a price that you can
afford...
