Inrush current limiter (hydraulic lifts)
Electronic inrush current limitation for hydraulic lifts
Electronic inrush current limiter (soft start) to 1.2 or 1.5 times nominal current (older lift systems were driven with a star-delta connection.
The three phases of the alternating current network were simply switched on differently. This led to current peaks in the region of 3-fold nominal current during switching).
