    Tips: Functions of the parallel capacitance of the contactor coils

    1. The voltage at both ends of the capacitor cannot be specially changed, and after the capacitor is connected, the reverse electromotive force of the coil can be delayed and reduced, interference is reduced, and the life of the contact is prolonged.
    2. A proper resistor in series with the capacitor can dampen the oscillation, reduce the time of over-voltage, and achieve better results. This is the resistance-capacitance absorber.
    3. The larger the capacitance, the smaller the impedance and the higher the passing frequency. But in fact, most of the capacitors over 1μF are electrolytic capacitors, which have a large inductance component, so the impedance will increase when the frequency is high.
    4. The key is that there is parasitic inductance on the capacitor, and the capacitor discharge circuit will resonate at a certain frequency. At the resonance point, the impedance of the capacitor is small. Therefore, the impedance of the discharge circuit is the smallest, and the effect of supplementing energy is also the best. For capacitors of the same capacity, the more small capacitors in parallel, the better. Voltage resistance value, temperature resistance value, capacitance value and ESR are several important parameters of the capacitor, and the lower the ESR, the better.

    High quality 65amp DC contactor
    I have used it for so long to review it just to see the effect. This 65amp DC contactor really makes me feel at ease. It is also very convenient and safe to use, and it has a formal agency certification. I believe that with its help, I will never worry about the starting and protection of electric locomotives anymore.
