The High Frequency Welding Machine Film Capacitor specifically supplied by Piner Manufacturer is an industrial high-frequency high-power customized type of metalized polypropylene (MKP/CBB) film direct current capacitor. It is designed for the high-frequency induction resonance, high-power continuous energy storage, high-current continuous current carrying, core working condition of high-temperature temperature rise in the industrial high-frequency welding machines. It is optimized for the resonant characteristics and low loss in the 50kHz - 500kHz mainstream welding working frequency band. It is a key resonant energy storage component for the high-frequency induction heating welding system to achieve the conversion of electrical energy - high-frequency induction energy - thermal energy. Compared to the general high-frequency MKP capacitors, this model has been upgraded in terms of high-frequency low-loss resonance, continuous high-current carrying, high-temperature anti-discharge, and resistance to high-frequency cyclic charging and discharging. It perfectly meets the continuous industrial operation requirements of various high-frequency welding machines such as metal tube connection, sheet spot welding, wire melting, and metal brazing, and is the core supporting component for improving the induction conversion efficiency of the welding machine, stabilizing the welding temperature, and extending the overall service life of the machine.
Precise matching of high-frequency welding frequency band: Specifically customized for the mainstream high-frequency welding machines operating at frequencies ranging from 50kHz to 500kHz
High-frequency wide-band low-loss characteristics: Leveraging the low-loss advantage of modified polypropylene film
Super strong continuous large current carrying capacity: Capable of withstanding the current load of continuous welding machine operation, electrode without erosion, core body without thermal breakdown, suitable for 24-hour uninterrupted operation of high-power industrial welding machines;
Excellent high-voltage and anti-arc discharge performance: Rated voltage covers 400V to 1500V DC, customizable for higher voltage specifications
Wide temperature range high-temperature stable operation: Rated operating temperature -40℃ to +110℃, suitable for the temperature rise of the welding machine cavity during continuous operation
Resistant to high-frequency cyclic charging and discharging: Under full rated voltage and temperature, the number of charging and discharging cycles is resistant
