We will miniaturize and lighten the winding-type transformer, which has been difficult to downsize, to reduce leakage inductance and radiated noise!
Peyton's planar transformers can mix a winding type on the primary side with a planar type on the secondary side. By converting the winding type transformer, which has been difficult to downsize, into a planar type (laminated type), we achieve a compact, thin, and lightweight transformer. This significantly reduces the radiation noise and leakage inductance that are disadvantages of winding types, and the laminated design also offers advantages against skin effect and proximity effect. Additionally, unlike winding types, our molded products have less variation, which helps reduce the unseen costs for customers who wind coils. It is also possible to include total loss specifications in the documentation.
With over 50 years of experience, we offer consulting services for noise control suitable for your company's electromagnetic environment.
Our "Noise Trouble Consultation Room" was established in 1983 as a specialized technical department for noise trouble measures. Since then, we have received consultations on various noise issues amounting to 3,000 cases annually and have worked on their resolution. To date, we have accumulated a vast number of achievements and rich experience, receiving significant recognition from various sectors.
It reliably protects information processing devices, equipment, systems, etc., from high-frequency noise interference.
The noise cut transformer is a barrier wave blocking transformer that serves as an isolation-type noise prevention device. It reliably protects information processing devices, equipment, and systems from high-frequency noise interference even in the worst electromagnetic environments. The "Noise Cut Transformer Barrier Wave Blocking Transformer Comprehensive Catalog" includes various models such as the standard model "NCT-F1," which is easy to use with both 100V and 200V input/output, the "NCT-F3 and F4" models that consider aesthetic design, and the mid-capacity "NCT-F5, F6, and F6-CE" models that pursue cost performance. [Featured Products] ○ NCT-F1 ○ NCT-F3 and F4 ○ NCT-F5, F6, and F6-CE ○ NCT-J ○ NCT-I1 and I2, among others For more details, please contact us.
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.
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 conventional 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 products, we can also produce units at your desired voltage through made-to-order production, 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.
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 it is suitable for achieving a high level of prevention effectiveness. Compared to the NCT-F series, a higher attenuation rate can be achieved. It is designed faithfully according to the principles of noise prevention, featuring a triple shielding body and a robust, low-impedance outer casing, and is constructed with shapes and materials that shield all conductive parts, including terminals and lead wires.
The core, coil, shield, case, and even the lead wires have all been manufactured in strict adherence to the theory.
This product has been developed through efforts since 1960, revealing what is theoretically the most superior, and has achieved commercialization by improving manufacturing methods and materials (with patents obtained for its structure and manufacturing methods). Its core shape and coil arrangement are of an off-axis eccentric twist, exhibiting outstanding performance from several kHz to GHz. It is mainly used in laboratories, space development, laser-related equipment, precision experimental instruments, and for measuring minute signals.
This model has obtained certification for the insulation material UL standard "UL1446" and the structural UL standards "UL5085-1, UL5085-2."
This is a medium-capacity noise filter transformer that complies with UL standards. It is a model certified under the UL standard for insulation "UL1446" and the UL standards for construction "UL5085-1, UL5085-2." This product can be custom-made to meet your specifications.
![[Case Study] When the overseas compressor operates, a leakage current alarm is triggered.](https://image.mono.ipros.com/public/product/image/804/2000680989/IPROS72096848734106339018.png?w=280&h=280)
I want you to clarify the cause of the alarm sounding! Here is an introduction to noise countermeasure examples!
Since it has already been confirmed by the customer that there are no abnormalities in the equipment's insulation, 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. Under normal circumstances, 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 high-frequency noise dispersion. Upon confirming with the customer, it was noted that a noise reduction product is also installed on the equipment's compressor, so we focused our investigation on the surrounding area. *For more details, please refer to the PDF document or feel free to contact us.*

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 10 kHz to 1 GHz, and common mode from DC to 1 GHz. In comparison, the attenuation range of typical LC filters for power supplies is from 100 kHz to 30 MHz, making the bandwidth of attenuation extremely wide among noise prevention devices.

Resolving 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; however, during the actual concert, a 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 since then, the phenomenon of the LED screen blacking out has not occurred. [Case Summary] ■ Problem: A part of the LED screen blacked out ■ Product Introduced: Noise Cut Transformer ■ Effect: The phenomenon of the LED screen blacking out has not occurred *For more details, please refer to the PDF document or feel free to contact us.

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 implementing noise countermeasures for high-frequency noise generated within their steelworks by installing noise filters on the power lines of their equipment and attaching ferrite cores to the power cables. However, the issues were resolved only in one or two locations, while many other areas remained problematic. In environments where various frequencies of noise coexist, it is believed that countermeasure products targeting only specific frequencies may not yield sufficient results. Therefore, we proposed the introduction of the "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 problems. [Case Overview] ■ Problem: Despite using countermeasure products for noise control, issues remain unresolved. ■ Product Introduced: 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.

By using an amorphous core, we have reduced no-load loss to about 1/4 to 1/6 of conventional products, achieving the highest efficiency in energy-saving effects.
When using amorphous alloy strips for iron cores, compared to magnetic materials such as silicon steel sheets with crystalline structures, the rotation of atoms becomes easier when the magnetic flux changes, resulting in reduced hysteresis loss (loss during magnetic flux passage). Additionally, due to the thinner plate thickness, eddy current losses are also minimized. Therefore, amorphous iron cores reduce iron loss compared to conventional silicon steel plate iron cores. Transformer losses can be broadly categorized into two types: "no-load loss," which occurs regardless of the load, and "load loss," which varies with the load current. No-load loss primarily refers to iron loss occurring in the iron core. Load loss, known as copper loss, is due to the resistance of the transformer windings caused by load current. Amorphous transformers focus on minimizing no-load loss among these losses. Since transformers are long-lasting products, reducing no-load loss can lead to significant energy-saving effects.
Reduce no-load losses in Scott-connected transformers, contributing to energy savings and CO2 reduction!
The "Amorphous Scott Connection Transformer" is used to convert three-phase AC power into single-phase AC power while minimizing the no-load loss (standby loss) of the Scott connection transformer, contributing to energy savings and CO2 reduction, particularly demonstrating its effectiveness in emergency power supplies. Conventional Scott connection transformers were made with silicon steel cores, but Jibu Electric has utilized amorphous alloy for the core, reducing no-load losses to about 1/4 to 1/6. The importance of emergency power supplies (generators) has significantly increased in factories, office buildings, and hospitals in case of emergencies. To simultaneously extract single-phase and three-phase power, a Scott connection transformer is necessary, and the Amorphous Scott Connection Transformer reduces no-load loss (standby loss) to 1/4 to 1/6. This allows for reduced generation costs when emergency power is needed, and when converted to electricity charges, it can be reduced to about half compared to conventional products.
