Decisive effect against noise leakage from inverters! It can also be widely used for other three-phase applications.
This is a "Noise Cut Transformer" developed to prevent malfunctions and communication disturbances caused by noise associated with the rapidly increasing use of "general-purpose inverters." Of course, it can also be used for other applications. The noise generated by conventional inverters has been difficult to sufficiently mitigate using LC filters and similar methods. This is due to the presence of a significant amount of noise in the frequency range below 100 kHz, where the effectiveness of the filter diminishes, as well as issues such as leakage current when using filters and the influence of grounding conditions and the impedance of power and load devices. The NCT-J is a trump card that can solve these problems all at once.
