A few weeks back I posted a query as to how one might parallel two
Astron RS50M power supplies to power a Hercules II.
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. :)
