UL・CE compliant compact lightweight energy-saving transformer

UL・CE compliant compact lightweight energy-saving transformer

A compact and lightweight NCW transformer has been made compliant with UL and CE marking.

Our unique iron core winding technology allows for a compact and lightweight design, achieving less than 70% of the size of conventional transformers. Additionally, by significantly reducing no-load standby current due to high efficiency, we have realized energy savings. This greatly contributes to reducing operating costs and saving space. *Addendum on November 26, 2021* We sincerely appreciate your continued patronage. Regarding our transformer products (NCW/KBSW), we have been experiencing delays in the arrival of components due to shortages of raw materials from various suppliers, and the situation has worsened. We have been taking measures to secure component inventory for stable supply, but it has now become difficult to cover delivery times. The delivery dates are currently "undetermined." We sincerely apologize for any inconvenience this may cause, but please note that the components used and their availability may vary by product, and we will provide individual updates accordingly. We appreciate your understanding in this matter.

Introduction to the Payton Planar Transformer

Introduction to the Payton Planar Transformer

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.

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 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.

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 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.

Noise Cut Transformer NCT-G

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 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.

[Case Study] When the overseas compressor operates, a leakage current alarm is triggered.

[Case Study] When the overseas compressor operates, a leakage current alarm is triggered.

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.*
