Kungani ukhethe uchungechunge lwe-LKE?
Uma uhlelo lwakho lubhekene:
✅ Ukushisa kwe-capacitor okubangelwa ukushintshashintsha kwemvamisa ephezulu
✅ Ukwehluleka kwemishini okubangelwa ukudlidliza
✅ Ukukhathazeka kwesikhathi sokuphila ezimweni zokusebenza ezishisa kakhulu
✅ Izidingo zobuningi obukhulu ngaphakathi kwemingcele yesikhala
Uchungechunge lwe-YMIN LKE lubeka uphawu olusha lwama-capacitor e-electrolytic e-aluminium esezingeni lezimboni ngokuphila kwawo kwamahora ayi-10,000, imvamisa ephezulu, izici zokumelana okuphansi, kanye nokuzivumelanisa nezimo zokushisa okugcwele. Lunikeza ukumbozwa kwe-voltage ephelele kusukela ku-10V/1500μF kuya ku-250V/120μF futhi lusekela imiklamo ye-electrode eyenziwe ngokwezifiso.
