DC Power supply

[EASI54]

I bought a used Icom-m710 SSB and it didn't come with any of th
necessary accessories to get it up and working. So I started lookin
for a power supply, and the manufacturer of the radio recommends thei
PS-66 DC-DC converter for a 24 volt setup to drop it down to 13.6 volts
New, it COSTS ABOUT $1100!!!!!!

Anyone know of a cheaper way to do this?

Just one idea... How about a dedicted 12v battery for the SSB. Then
use a smaller down converter (not sure if you can find a 24v --> 12v
charger or not...). The battery handles the high current drawns
during trans,, and then the 12v battery can 'recharge' between usages.

Depends on your equipment specification.
If your equipment draws less than 10A,
you can try DC-DC chips.
There are various IC chip that converts from voltage to voltage. They are
easily available nowadays.

Not sure if it works on your system.
You can give it a try.

For a start you can try the following web on voltage conversion information,
to source for your needs,

Numar makes some really nice 24-32Vdc to 12Vdc@35Amp Marine

DC to Dc Converters, for about half that price. You actually may
only need a 20Amp version for that Icom Radio, which will be a bit
cheaper.

Check out Powerstream DC/DC converters. They have 24/12 models up to 40
amps continuous, 80 peak for under $200. You would probably be fine with
the 40 amp peak model that can handle 30 amps for 10 minutes and 20
continuous for $136. http://www.powerstream.com/dc-buck-boost.htm
