OSKαR® – Online voltage correction with adaptive control

OSKαR® is an active three-phase line voltage regulator with advanced power electronics. It keeps the magnitude and phase of the mains voltage continuously and highly dynamically at the setpoint; typical voltage dips are simply cycled through. The system can be scaled for any power requirement via the number of modules. The efficiency is around 98.5 %.

OSKαR® is simply connected in series between the supply transformer and the equipment. Normally, no further changes or adjustments are required. In particular, the fuse protection can be maintained, since the short-circuit current is only slightly affected by the installation. In case of emergency, short-circuit currents are safely routed via a multiple-redundant bypass system so that the customer’s protective devices trip reliably. OSKαR® itself is designed to cope with such events without any problems.

• Almost unchanged mains short-circuit performance
• Robust overload capacity
• Economic solution (no energy storage = low maintenance costs; high efficiency = low operating costs)
• High scalability to the required performance due to modular design
