(Submission of materials) Why is a noise-canceling transformer necessary?
Introducing examples of noise generation in a 7-panel comic! It clearly explains why noise reduction is necessary!
Inverters, which started with skyscrapers and high-tech factories, are now also used in ordinary households. In familiar settings, they control motors used in air conditioners and elevators, contributing to comfortable operation. However, sometimes unnecessary electricity (noise) is generated, which can negatively affect surrounding devices. We often hear comments like, "Noise countermeasures are important, but I don't really understand them." In this book, we clearly explain an example of noise generation through a 7-panel comic, so please take a look. On the back, we provide more detailed content and introduce corresponding products as well. For more information, please download the catalog or contact us.

![[Noise Countermeasure Case] System Abnormal Shutdown in Plasma Arc Welding](https://image.www.ipros.com/public/product/image/c53/2000680963/IPROS80509339728363700309.png?w=280&h=280)
[Noise Countermeasure Case] System Abnormal Shutdown in Plasma Arc Welding
Pilot arc affects the PLC! The cause of the system's abnormal shutdown might be noise?
Company C, a parts processing manufacturer, automated the plasma arc welding process to reduce labor. The system configuration involves moving the workpiece using a servo motor and performing the welding operation once it reaches the designated position. In the automation process, position detection sensors and proximity sensors were installed, and safety measures were implemented simultaneously. Since there are multiple parts to be welded, the control system was pre-programmed, allowing for changes in control patterns for each target during operation. However, the system occasionally froze, and due to a malfunction that caused the pre-set programs to be rewritten, abnormal system shutdowns occurred. *For more details, please refer to the PDF document or feel free to contact us.*

[Noise Countermeasure Example] The analog signal from the weighing controller is unstable.
In a servo-based weighing system, the analog signal from the weighing controller fluctuates.
At Company B's factory, which manufactures plastic products, there is an automatic weighing machine for resin raw material pellets that are transported by a conveyor belt. This system inputs the analog signal output from a device that detects the gate's opening degree via a potentiometer into a PLC for control, and sends signals to a servo driver for control. While operating this system, a problem occurred where the gate opened and closed in small increments, making accurate weighing impossible. If this continues, it will significantly impact product production... This case was related to "high-frequency noise propagating through the air." *For more details, please refer to the PDF materials 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.
