Factory Supply Ac Capacitor For Welding Equipment - High power capacitor for power electronics – CRE
Factory Supply Ac Capacitor For Welding Equipment - High power capacitor for power electronics – CRE Detail:
DKMJ-S Specification
CRE has been a world leader in high-performance film capacitor technology design for 10 years. We produce dry-wound capacitors, from 100VDC to 4kVDC. A key feature of CRE High Power is Controlled Self-Healing technology. This enables the capacitors to continue to function without catastrophic failure by effectively insulating any microscopic conduction sites within the dielectric.
While power film capacitors remain functional throughout their operating life, the initial capacitance value will decrease at a rate dependent upon the applied voltage and hot spot temperature. Our standard designs provide < (2-5)% capacitance loss over 100,000 hours lifetime at nominal voltage and a 70ºC hot spot temperature, while application specific designs can be provided on request. Various series of CRE High Power Capacitors are available for DC filtering, Protection, Pulse Discharge, Tuning, AC filtering and Storage applications.
