Filter capacitor 12uf 3000VDC

DC filter capacitor 500uf support the specification, "Seif card" DC filter capacitor (locomotive power capacitors) are key components of modern variable-speed drive. Modern variable transmission with a static frequency converter, wherein the semiconductor switching action produces a lot of spurious signals, therefore, need a capacitor in the circuit to filter, to eliminate the ripple and harmonics. The self-healing metallized film capacitors can be used as a DC intermediate circuit connections and harmonic filter to use, but also can be used as the control circuit and clamp snubber capacitor. The capacitors are safe metallized film, a unique flattening and welding technology, advanced shock and equalizing both structural design and other innovative technology flows to ensure the stability and accuracy of the capacity, low inductance, a substantial increase in resistance to high voltage , inrush current strength. Such a capacitor can be designed to dry flame structure, the structure can also be designed as a high quality oil, vacuum impregnation, improved insulation resistance and capacitance stability, life reliability of the capacitor, and a good heat dissipation, to ensure the long capacitor running time. The capacitor dielectric is low loss metallized polypropylene film, the film is self-healing import-based film, sheet resistance gradient applied safety film deposition using patented technology. A fully automated equipment film wound into a cylindrical, application no sense of winding technology, the core technology inside a thin copper connection makes smaller inductance capacitor production, over-current overvoltage ability. The solvent medium is filled in the capacitor in order to isolate the air between the electrodes, there is no fill media protection, metal plating layer will be oxidized, metallized film will more and more be self-healing, smaller capacity of the capacitor, loss growing. Features DC filter is applied to the circuit, you can replace electrolytic capacitor equivalent series resistance, can withstand a greater ripple current small inductance has self-healing and long life aluminum, resin potting applications of wind power, solar power generation upconverter transport such as: electric cars and hybrid welding equipment, elevators, motor-driven Compliance with Standards Standards IEC 61071, IEC61881 operating temperatures (Case) Operating temperature (housing) -40 ° C to + 70 ° C storing temperature Storage temperature -40 ... + 85 ° C ΘHOTSPOT hot temperatures ≤85 ° C Capacitance tolerance capacitor tolerance ± 5% or ± 10% tanδ0 loss 2 x10-3 (100Hz, 20 ° C) Test voltage terminal to terminal UTT terminals Test voltage 1.5 URMSfor 10 seconds Test voltage terminal to case UTC test voltage between terminals and the shell 3kV - 50Hz for 60 seconds Permissible relative humidity relative humidity allowed 75% Annual average≤95% on 30 days / year, the annual average humidity of 75%. 30 days / year Climatic category IEC climatic category 40/85/21 Capacitance deviation in the operating temperature range of -25 ° C to + 70 ° C to + allow capacity changes in the value ± while working at -25 ° C temperature under 70 ° C 1.5% max on capacitance value measured at + 20 ° C maximum deviation of ± 1.5% relative to 20 ° C measured Case components shell components Aluminium, plastic, 304 stainless steel aluminum casing, plastic, 304 stainless steel terminals Terminals Tinned brass fastons or Installation screws tinned copper screw mounting location anywhere in Life Expectancy Whatever Position inverter DC link capacitor life expectancy 500UF .jpg ≥100.000 hours at Un Failure quota within the failure rate of 50 FIT Recommended torque for screw connections recommended torque threaded connection M6-3Nm, M8-6Nm support DC filter capacitors are cheap, and shipping. Product warranty for two years, one year replacement. The company stresses credibility and quality of security, customers purchasing rest assured that with more ease.
