Introduction to the features of the TNPL series LED lighting system 2

Introduction to the features of the TNPL series LED lighting system 2

1/1000 unit dimming! LED dimming control device that achieves ultimate energy savings.

The TNPL series is a flicker-free and eye-friendly system that can dim down to 1/1000 units. By finely adjusting the brightness, it can provide the necessary amount of light only where it is needed. Additionally, it is possible to reduce installation costs by reusing existing fixtures. Furthermore, by removing insulation during the conversion from AC to DC, noise generation is minimized. 【Features】 ○ Dimming in 1/1000 units ○ Reuse of existing fixtures ○ Noise reduction ○ Ultimate energy savings For more details, please contact us or download the catalog.

[Power Supply Design Proposal Example] Replacing Obsolete Products with Noise-Resistant Design

[Power Supply Design Proposal Example] Replacing Obsolete Products with Noise-Resistant Design

We propose a circuit design and implementation that is resistant to noise! It is operating without any issues!

The customer in this case was using a DC power supply for industrial equipment from another company, but it had many issues and was discontinued. After conducting a failure analysis, we found that the problems were not due to individual components, but rather inherent design flaws, such as poor noise immunity. In response, we proposed a circuit design and implementation that is resistant to noise. Before our design was implemented, the customer experienced frequent troubles, but after using the power supply designed by us, they have been operating without any issues. [Challenges] ■ Used a DC power supply for industrial equipment from another company ■ Had many issues and was discontinued *For more details, please refer to the related link page or feel free to contact us.
