[Case Study] Pharmaceutical Manufacturer C Research Institute

Unexplained stoppage of the centrifuge, what is its true nature? Introducing a case that achieved stable operation of research equipment!

At the C Research Institute, research and development of new drugs is being conducted, and many facilities are operational; however, there were issues occurring. It was speculated that the cause might be the deterioration of the power supply environment due to voltage fluctuations, but this remained merely a hypothesis, and we were in trouble. Since there are various factors that can deteriorate the power supply environment, we first proposed the introduction of cost-effective high-frequency noise countermeasure products and provided a trial unit. When we installed a "Noise Cut Transformer" on the centrifuge to check if the situation would change, the issues that had occurred daily completely ceased from the very first day of installation. Subsequently, we introduced the solution to other devices that had experienced issues, and those devices also stopped having problems, achieving stable operation of the research equipment. [Case Summary] ■ Problem: Unable to identify the cause of the issues ■ Proposal: Cost-effective high-frequency noise countermeasure products ■ Introduced Product: Noise Cut Transformer ■ Result: Troubles resolved with high-frequency noise countermeasures ■ Conclusion: It is important to implement measures suitable for the factors causing disturbances that deteriorate the power supply environment. *For more details, please refer to the PDF document or feel free to contact us.

[Case Study] POS System Development Company A

Is it prohibited to use while charging? We will introduce cases where the cause was identified and the trouble was resolved!

Company A, a manufacturer of POS system development, has been focusing on the spread of tablet-type POS systems and has delivered them to many stores. However, recently, complaints have been received from newly supplied stores stating that "malfunctions occur, making it impossible to operate." Company A conducted daily investigations to resolve this issue, but identifying the cause proved difficult, leading to a prolonged period of uncertainty. We estimated that the conductive noise transmitted through the power line was entering the tablet via the charger, causing the troubles. We proposed the "Noise Cut Transformer," which can eliminate power noise. After installation, the troubles completely disappeared, and normal operations were restored. [Case Summary] ■ Problem: Unable to operate while charging ■ Product Introduced: Noise Cut Transformer ■ Effect: Troubles completely resolved *For more details, please refer to the PDF document or feel free to contact us.

Noise Cut Transformer NCT-R3-J6

The latest three-phase model that improves noise reduction performance while considering safety and ease of use.

The "Noise Cut Transformer" has improved noise attenuation performance, safety, and ease of use. It is a disturbance wave blocking transformer. Focusing on the fact that various noise disturbances are caused in different environments by high-frequency noise below 150 kHz, which is not covered by major EMC standards such as the IEC 61000-4 series, we have generally enhanced the noise attenuation performance, particularly in the range of several tens to several hundred kHz. Additionally, not only the conductive parts such as terminals and coils but also the core part is enclosed in a case to prevent contact, making it safer to use.

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

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.

Noise Cut Transformer NCT-G

We have received high praise from cutting-edge research institutions, starting with the field of nuclear physics.

The coil's positioning is structured in an eccentric axis and eccentric core format, making it particularly effective in high-frequency areas and suitable for achieving high prevention effects. Compared to the NCT-F series, a higher attenuation rate can be achieved. It is designed faithfully to the principles of noise prevention, featuring a triple shielding body and a robust, low-impedance outer casing, constructed with shapes and materials that shield all conductive parts, including terminals and lead wires.

[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

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.

Discovering the Charm of Noise-Cutting Transformers Again! Vol. 2

When used indoors where impulse coordination is maintained, it can withstand induced lightning!

This booklet introduces impulse voltages as defined by the overvoltage category/JIS. The standard impulse withstand voltage for the "Noise Cut Transformer" is 5kV (5000V). Up to an impulse voltage of 5kV (standard impulse voltage of 1.2/50μs as defined by JEC-0202), it can protect equipment from induced lightning without insulation breakdown. If you have concerns about impulse coordination or when using it in outdoor panels, please consider the NCT-K type or I4 type with an impulse withstand voltage of 10kV, or the NCT-K type and P type with an impulse withstand voltage of 30kV.
