You want a crowbar and a fuse.
Avoid switchmode supplies like the plague.

This is a link to one review of the RS-10a:

This link to a dagram shows a fuse:

A long time ago in a different life (20+ years ago) I was responsable
for the operation of a 2 mtr repeater and I picked a Atron supply that
is still chugging along with no trouble. I don't remember which Astron
but at least back then, they made great supplies.

I added a surplus magnetic circuit breaker between the output of my
Lambda ~15A 12V supply and my equipment, followed by a seperate
fast acting, no falses ?(so far) crowbar. This is the BEST OVP (Over
Voltage Protector) I have seen in 30+ years of working in electronics.
Added a heavy si diode wired to shunt reverse voltage to ground.
This is located in the power distribution section of my system. With
this
I can directly power my radio room from my car, for emergencies, and
won't have to worry abvout areverse connection,or nasty spikes damaging
my equipment.
Power supply on floor feeds voltage/current monitoring with R&OVP and
breakers to protect and alllow me to power down sections to reduce
power load. Sounds complex and expensive, but it wasn't and I bought
everything surplus. The distirbution sections has stayed "the same" for

the last 20 years, I have gone through several power supplies. I have
connections for 2 lead acid gell cells, and an outside connection to
allow
an external +12V power source.

Think modular.
Build it in sections as needed.

You know what, screw Ebay. My R75 is almost brand new and I love my Lowe
HF-150 so why not "splurge a little" and buy a new one? I just bought a
brand new Astron RS-7a. $45.80 was the cheapest I could find it plus $12
shipping. It weighs 10lbs.

I think I did the right thing buying a new one.

Guess what? I cancelled the damn order. After looking carefully thru the
finer print, it seems they are in "perfect condition returns" That why
$45.80

Hate that crap. You see these deals on radios till you call and finally
found out "our loss is your gain" is that are "open box" items or "factory
refurbished"
