Hitachi-Hirel offers iDip to supports VFD operation when input three phase reduce to 50% or any one phase reduces to zero keeping balance two phases in healthy condition for 2 seconds.
When operated through inverter, power dip causes reduction in motor RPM. With iDip, no motor RPM loss during 50% line voltage dip or single phasing for 2 seconds.
iDip supports the inverter in maintaining DC bus voltage and motor rpm during power dip conditions. There will be no change in the speed of the running motor.
