Lighting control via PLC communication (for overseas)

Lighting control via PLC communication (for overseas)

No new communication wiring work is required! We will use PLC to control one of the lighting control standards, "DALI."

This is an introduction to overseas lighting control using PLC communication. We control one of the lighting control standards, "DALI" (Digital Addressable Lighting Interface), using PLC. (A DALI module has been added to our PLC device.) The control data is converted to the DALI protocol at the PLC terminal device. By using PLC, it is possible to use the DALI standard without the limitation of a maximum distance of 200m (host-lighting distance) and 64 connections. 【Benefits of HD PLC Standard】 ■ Stable communication with wired connections ■ No need for new communication wiring work ■ High communication speed ■ Easy installation with one-touch settings, even for light users ■ Capable of supplying higher current and voltage than Ethernet PoE *For more details, please refer to the PDF document or feel free to contact us.

Achieving high-speed switching operation! "Power supply for xenon arc lamps"

Achieving high-speed switching operation! "Power supply for xenon arc lamps"

Break away from IGBT technology! High performance with high-speed switching (FET) operation. The device becomes compact, and simplifying the control circuit improves reliability.

The "Xenon Arc Lamp Power Supply" is a product that can control large currents simply by applying a small voltage to the gate of a FET. By adopting FETs, it achieves over 500W at frequencies above 50KHz. Higher output is also possible. The simplification of the circuit improves reliability, and it employs forward coupling (FCC method) and FETs. *FET = Field Effect Transistor We provide precise proposals for companies that currently use the conventional IGBT method! 【Features】 ■ High capability with high-speed switching ■ Large current with small voltage input ■ Improved reliability through circuit simplification *For more details, please refer to the PDF materials or feel free to contact us.

[Information] The Secret of Low Noise

[Information] The Secret of Low Noise

Introducing a design that does not produce the "noise," which is the fate of switching power supplies.

In this document, we introduce how the power supplies handled by Daitron achieve low noise. Generally, switching power supplies generate noise due to the ON/OFF switching. Daitron has made improvements to this switching method. We will reveal the secret of a "power supply that does not produce noise" rather than just a "power supply that suppresses noise." [Contents] ■ Hard Switching and Soft Switching ■ Fundamental Issues of Switching Power Supply Noise ■ Summary *For more details, please refer to the PDF document or feel free to contact us.
