The PhaseCap HD series is a further development of the PhaseCap Premium series, covering the output power range above 40 kvar through 60 kvar with a single capacitor in a cylindrical aluminum can. The PhaseCap HD is intended in particular for industrial applications which demand a long service life, constant capacitance and a high inrush current capability of up to 300 times the rated current. Such applications require typical power steps of 25 kvar or 50 kvar switched via each capacitor contactor by a PFC controller. This MKK AC series was developed to increase the packing density per capacitor bank and cut component costs. PhaseCap HD capacitors are gas-impregnated, with wavy cut and a triple safety system. They are available with rated voltages of 400 V AC to 525 V AC at 50/60 Hz and outputs from 40 kvar to 60.0 kvar.
