HES Series
B-5
Application 3
Used to improve the input power factor, to reduce harmonics and provide protection from AC line
disturbances. (Surges, switching spikes, short interruptions, etc.). AC line reactor should be
installed when the power supply capacity is 500kVA or more and exceeds 6 times the inverter
capacity, or the mains wiring distance
≤
10m.
Question
When power capacity is too large, line impedance will be small and the charge current will be too
large. That may damage Hybrid Servo Controller due to higher rectifier temperature.
