Incoming 3 Phase Supply

All drives have full regeneration capabilities to the common DC buss. With a common DC buss, the
energy produced by a regenerating drive, ie: entry bridle drives during line run can be used to power
the exit bridle drives thereby significantly reducing the incoming power requirement from the three
phase supply.

Drive regeneration is used during an Emergency Stop to quickly stop the strip so snubber resistors are supplied to dissipate the excess energy.

One AC Drive isolation transformer is included for the new AC Drives.
