Noise Cut Transformer NCT-J

Noise Cut Transformer NCT-J

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 disruptions 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 with LC filters and similar devices. This is due to the presence of a significant amount of noise in the frequency range below 100 kHz, where the effectiveness of the filters diminishes, as well as issues such as leakage current when filters are used, 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.

Noise Cut Transformer NCT-I3

Noise Cut Transformer NCT-I3

It is a low-cost model equipped with basic performance. It is very convenient when connecting loads such as measuring instruments and audio equipment via a plug.

This is a small, low-cost "Noise Cut Transformer" developed with a focus on general-purpose electronic devices for mass production and portable electronic devices. By utilizing a newly developed noise prevention mechanism (which has been patented), it effectively blocks normal mode noise across a wide frequency range that cannot be prevented by standard isolation transformers or shielded transformers, thereby significantly improving the noise resistance of the connected devices. Additionally, its wideband common mode noise blocking capability protects the load devices from surges caused by induced lightning. In addition to standard voltage models, we can also produce units with custom voltages upon request, allowing for replacement of the power transformer in the connected devices. Furthermore, it can eliminate the need for other noise prevention components such as power filters.

[Case Study] An alarm for leakage current is triggered when the overseas compressor operates.

[Case Study] An alarm for leakage current is triggered when the overseas compressor operates.

I want you to clarify the cause of the alarm sounding! Here is an introduction to noise countermeasure examples!

Since you have already confirmed that there are no abnormalities in the insulation of the equipment, we considered another possibility. Generally, high-frequency noise is generated from the compressor. Typically, some noise reduction product is installed on the compressor to prevent the high-frequency noise generated from affecting surrounding equipment. In principle, that noise reduction product should be able to sufficiently prevent the outflow of high-frequency noise. However, when several adverse conditions overlap, that noise reduction product can sometimes become a cause of dispersing high-frequency noise. Upon checking with the customer, it was confirmed that a noise reduction product is also installed on the compressor of the equipment, so we focused our investigation on the surrounding area. *For more details, please refer to the PDF document or feel free to contact us.*

Booklet: Rediscovering the Charm of Noise-Cutting Transformers! Vol. 1

Booklet: Rediscovering the Charm of Noise-Cutting Transformers! Vol. 1

Extremely wideband among noise suppression elements! Lightning surge voltage can also be significantly attenuated!

This booklet introduces the wideband attenuation characteristics of the "Noise Cut Transformer," which can attenuate not only noise but also "lightning surges." The attenuation range for line noise that can be prevented covers normal mode (between lines) from 10kHz to 1GHz, and common mode from DC to 1GHz. In comparison, the attenuation range of typical LC filters for power supplies is from 100kHz to 30MHz, making the bandwidth of attenuation extremely wide among noise prevention devices.

[Case Study] Video Production Company M

[Case Study] Video Production Company M

Solving the blackout of large LED screens! To provide customers with beautiful visuals!

The video production for a concert with an audience of 10,000 will be handled by Company M. During the preliminary rehearsal, the LED screens displayed images without any issues, but during the actual concert, part of the large LED screen suddenly blacked out. Our company conducted an immunity test using a noise simulator. Based on the test results, we determined that the cause of the trouble was likely high-frequency noise. Based on the test results, we recommended that Company M install a "Noise Cut Transformer" on the power line of the video controller. Since then, Company M has ensured that this product is installed during concerts, and the phenomenon of the LED screen blacking out has not occurred again. 【Case Summary】 ■ Problem: Part of the LED screen blacked out ■ Product Introduced: Noise Cut Transformer ■ Effect: The phenomenon of the LED screen blacking out has not occurred again *For more details, please refer to the PDF document or feel free to contact us.

[Case Study] Automatic Welding Machine Manufacturer D Company

[Case Study] Automatic Welding Machine Manufacturer D Company

Why isn't it resolved even though we are using countermeasure products? Here are examples of noise countermeasures for automatic welding machines!

Company D, headquartered in Tokyo, had been addressing high-frequency noise generated within their factory by installing noise filters on the power lines of their equipment and attaching ferrite cores to the power cables. However, the issues were resolved in only one or two locations, while many areas remained problematic. In an environment where various frequencies of noise coexist, it is believed that solutions targeting only specific frequencies may not yield sufficient results. Therefore, we proposed the introduction of a "Noise Cut Transformer," which can reliably eliminate a wide range of frequencies. As a result, the issues were successfully resolved, and the automatic welding machine began to operate without any problems. [Case Summary] ■ Problem: Troubles persist despite using countermeasure products for noise control. ■ Introduced Product: Noise Cut Transformer ■ Effect: Issues were successfully resolved, and the automatic welding machine operates without problems. *For more details, please refer to the PDF document or feel free to contact us.
