PhaseCap HD

Product Details

The PhaseCap HD series is a follow-on development of the MKK AC  series, covering the power range above 40 through 60 kvar with just one capacitor in a cylindrical aluminum case.   The PhaseCap HD is especially intended for industrial applications with demands for long life, constant capacitance and high inrush current withstand capability up to 300 · IR.  Such applications require typical power steps of 25 or 50 kvar switched by a PFC controller via each capacitor contactor. This MKK AC series was developed to  increase packing density per bank and cut component costs.
