Ron,
Good point.
In my case the voltage measurements were made at the load termi
never tried for long term use. I
like it due to its 3 lbs and my FT857 sets nicely on top.

I just read that manual. Seems each supply is adjusted
to 14.2V and should have 1% regulation. They do seem
to be very solidly hard-wired in parallel, but some
kind of jumper is used between all the modules in an
attempt to better share the current.
I hope their other supplies have a similar 1%
re
Thanks, that does sound like the unit that my friend
is using. I wasn't sure what they did to sum the
outputs, and I didn't know it had BB capability. I'd
think the voltage drop would be somewhat constant once
some load current was drawn.
My own repeater needs at least 14.0 Volts because I'm
using
Amplification... The voltage specs are shown on page *19* of the manual as
counted by Adobe; page 16 as counted by Samlex.

Thanks for all the replies. Too bad I never got my

it again.
I think the supply is something that was sold for a
limited time to offer some kind of redundancy. I don't
know if it's entirely capable of 100 amps, but it is

Bob,
I would expect a 20 ampere DC supply to regulate within 0.5 VDC, no-load to
full-load. Since the power supply in question comprises five 20-ampere
units in parallel, that should hold true.
As it happens, I have been running load tests under controlled conditions,

After a catastrophic failure of a Samlex SEC-1223, I won't use them ever
again.
