The EMKP capacitors are available in four heights from 160 mm to 265 mm and five diameters from 64 mm to 136 mm. The devices offer high current ratings up to 3 x 56 A and 3 x 104 A (depending on the bushing type), impulse currents up to 21.3 kA, very low self-inductance < 100 nH, low series resistance down to 0.6 mΩ, and capacitance values from 4.0 µF to 600 µF with a capacitance tolerance of ± 5 %.
Optimised for power factor correction, AC filtering, and harmonic filtering applications in three-phase mains, traction and industrial drives and converters, wind turbines, and solar inverters, the EMKP three-phase capacitors are metalized polypropylene film devices with self-healing technology.
EMKP 3-phase devices offer a high reliability rating of 120 FIT and a long lifetime expectancy of 100,000 hours at + 70 °C at rated voltage. The capacitors are specified for an operating temperature of – 40 °C to + 85 °C and meet IEC 61071-1, IEC 61881, and IEC 60831 standards. Terminal-to-terminal test voltage is 1.5 times the rated AC voltage for 10 seconds.
Samples and production quantities of the new EMKP three-phase series capacitors are now available.
