Delta's Ultron NT series Uninterrupted Power System (UPS) is used in critical loading of a certain international airport in the northwest phase 3 expansion project, including substations for central, north, and south flight areas as well as surveillance equipment for lights, so as to ensure the lighting safety of the flight area.

Considering that power use safety is criti∙cal to the flight areas, the users have specified clear needs for the UPS system, which include the following:
∙ During interruption of the city's power supply from power outage or other faults, the critical equipment of substations, transformers, and lighting stations need to continue operations before the power generator initiates.
∙ The loading of the lighting stations is complex and scattered, which has an impact on the front-end power supply, and the UPS needs to be able to cope with such load impact.

Relying on years of airport experiences, Delta has provided a total of 18 Ultron NT series UPS sets for the Phase 3 expansion project. Stand-alone systems are configured for each area, and the backup time is set to provide power based on different application scenarios. The advantages of the solution include:
∙ A small and centralized power supply method is adopted for each area, which solves the scattered loading and remote power supply problems at the flight zones while ensuring the safety of power supply to the equipment at substations, transformers, and lighting stations;
∙ The Ultron NT series UPS is an industrial frequency transformer and has enhanced anti-shock capability. By aligning the UPS system to front-end power quality equipment, not only can we protect the back-end power load, but also reduce the impact of the load on the front-end power distribution circuit.

On top of the aforementioned advantages, products in the Ultron NT series also allow users to set input/output rated voltage based on the application environment, and their N+X joint connection redundancy or system expansion can ensure the stability and reliability of its critical power load. The Ultron NT series UPS can continue to provide protection for equipment operations even in a scenario with 100% unbalanced load. It is not only cost-effective, but its reliable and high density design have also made it the ideal choice for safeguarding the power use safety of critical equipment and offers high-standard protection to airport applications.
