[Keysight Webinar] Pitfalls in Power Testing

[Keysight Webinar] Pitfalls in Power Testing

[Web Seminar] Pitfalls in Testing Kilowatt-Class Power Systems

The verification tests for high-power electricity are an important element supporting technological innovation, but the field is constantly faced with difficult trade-offs such as "accuracy or speed," "safety or scalability," and "cost or reproducibility." These challenges increase the risk of delaying development and can lead to increased energy consumption and equipment costs. In this webinar, we will introduce next-generation ATE system power supplies for high-power output testing that eliminate these trade-offs and help avoid typical pitfalls. We will showcase hardware with regenerative power, faithful emulation of battery consumption and load conditions, and software compatible with automation, all while providing safer, faster, and more efficient testing without compromising accuracy. ■ Event Overview Date: February 19, 2026 (Thursday) 11:00 AM - Venue: Online Participation Fee: Free (Pre-registration required)

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.
