Jim,
In the RM50, the "50" refers to 50 Amps ICS. The RM50 is rated at 50 Amps
ICS and 37 Amps continuous. This information was taken from the Astron
Service Manual which covers the RM50A, RM50M, RS50A, and RS50M. I realize
the RM50 is a different amp from the RS50, but the Astron Service Manual
makes no distinction for the ratings.

Actually, the Herc II is wired to accept two power supplies at the Molex
connector, each wired to half of the Herc II's output modules. I chose to
use a pair of RS70 Astrons, wiring one RS70 to each half of the Herc II.
The RS70s have a voltage sense terminal, and I wired them together. It
should be noted that the number 50 in Astron model number is NOT the current
rating in amps. I'm not looking at the manual or spec sheet, but the
current rating is about 25% lower. A pair of RS70s is a much closer match
to the Herc II. They're also pretty heavy, and they cost more. :)
