Re: current rating of transformers

Right....the DC motor/driver power is isolated. There is a slot
card in the back( like a giant PCI slot with fewer contacts. They
were big enough to drill and install connector lugs. According to
tests, there was nothing common to the 240Vac neutral input and the
two DC+ or - outputs. From there, isn't it common practice to keep
the DC power isolated throughout the drivers up to the motors?
