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.
