The energy-efficient and regenerative XVR supply units of the ctrlX DRIVE range generate a DC bus voltage from the supply voltage. Regenerative energy can be returned to the mains, and the DC bus voltage can be regulated on a constant level, independently of the supply voltage. The braking transistor and the emergency braking resistors which are used in the event of a failure of the supply voltage are already integrated.

Via the standard runtime, which enables the realization of most drive task, additional optional function packages for demanding applications are available. By means of various ordering options, it is possible to expand the hardware with the drive-integrated ctrlX CORE for nearly all automation applications.
