Application Example of AC Reactor 
Connected in input circuit 
Application 1 
When more than one Hybrid servo drive is connected to the same mains power and one of them is ON 
during operation. 
Problem: When applying power to one of the Hybrid servo drive, the charge current of the capacitors 
may cause voltage dip. The Hybrid servo drive may be damaged when over current occurs 
during operation.

Application 2 
Silicon rectifier and Hybrid servo drive are connected to the same power.   
Problem: Switching spikes will be generated when the silicon rectifier switches ON/OFF. These spikes 
may damage the mains circuit.
