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. :)
