    DC Reactor Price List

    The DC reactor, also known as the flat wave reactor, is mainly used on the DC side of the converter, and has more applications in general inverters. A DC current having an AC component flows DC reactorthrough the reactor. The main purpose is to limit the AC component superimposed on the DC current to a specified value, keep the rectified current continuous, reduce the current ripple value, improve the input power factor, and suppress the harmonics generated by the converter.
    ATO provides you a series of DC reactor for choice, 2 hp, 3 hp, 10 hp, 25 hp to 200 hp DC reactor. Here list some prices of DC reactor in the table below for your reference.

    The Role of DC Reactor

    A DC reactor is connected in series on each pole of the converter station. The inductance is about 0.4 ~ 1.0H. Its main functions are as follows:
    1. Prevent inverter commutation failure.
    2. Reduce the voltage and current harmonics in the DC line.
    3. Reduce the ripple factor.
    4. Limit the current in the rectifier when the line is shorted.
    However, it should be noted that the value of the inductor must ensure that the DC circuit does not resonate at the power frequency. The DC reactor can increase the power factor to above 0.9. Due to their small size, many inverters have installed DC reactors directly in the inverter. In addition to improving the power factor, the DC reactor can also reduce the impact immediately after the power is turned on. If equipped with both AC reactor and DC reactor, the power factor of the variable frequency speed control system can be increased to above 0.95.
