    Tips: 3 things should be known when using pulse plating rectifier

    1. Distance between pulse plating rectifier and plating tank

    In order to ensure that the pulse current waveform is not distorted and has little attenuation when it is introduced into the plating tank, the distance between the pulse plating rectifier and the plating tank is preferably 2-3m during installation, otherwise it will have a greater impact on the trailing edge of the pulse current waveform and the plating will not achieve the expected effect.

    2. Wire connection method of cathode and anode

    The wire connection method of the DC power supply is not suitable for the connection of the pulse rectifier. The output connection of the pulse plating rectifier. It is hoped that the inter-electrode capacitance of the two wires can offset the transmission inductance effect of the wire. Therefore, the best method for the cathode and anode wires is twisted pair After that, it is led to the edge of the plating tank, thereby keeping the pulse waveform unchanged.

    3. Selection of wires

    Because it is a pulse power supply, in order to avoid the trend effect, when selecting the wire, you should choose a multi-strand core wire as the connection line between the pulse power supply and the plating tank. The multi-strand core wire is twisted, and the line capacitance between it can offset its inductance effect.

    The specification of the wire must meet the rated current through it, because the current density of the pulse current is much larger than the average current density, so the current thermal effect generated by the current of the pulse power supply must be considered to ensure the minimum attenuation of the pulse power supply to the plating tank.

    ATO Responded
    The input AC power would be approx 10kW.
    Great to use
    Stable 300A three phase plating rectifier meets my requirements. Compared with many companies, I still choose ATO. It's not only good product quality and high cost performance, but also the good service and responsibility. The manufacturer is very professional. The voltage can be customized. According to the requirements of the factory, they recommended the most suitable model. It's really pretty good.
