Uninterruptible Power Supply [Assisting line operations and reducing the risk of production loss!]

Uninterruptible Power Supply [Assisting line operations and reducing the risk of production loss!]

【Ideal for BCP measures!】During a power outage, it continues to supply power, preventing forced shutdowns of equipment and reducing the risk of production losses.

The uninterruptible power supply "KE-0520 Series" is a device that continues to supply power to equipment during power outages caused by disasters, lightning strikes, or snow damage, thereby preventing various disadvantages. If no measures are taken against power outages, the cessation of power supply can halt production lines in factories, often resulting in significant drops in production volume. In the worst-case scenario, forced shutdowns due to power outages can cause equipment failures, which may prevent the production line from operating normally even after power is restored. By proactively preventing such situations, it is possible to mitigate the risk of production losses. Targeted measures against momentary power interruptions can also be implemented, focusing only on critical machinery and equipment rather than the entire factory. 【Features】 ■ Suitable for momentary power interruption measures for industrial machinery and medical devices ■ Avoids risks of loss in materials, labor costs, and production through power supply backup ■ Two types of energy storage devices are available: "EDLC" and "lithium-ion batteries" ■ Assistance is possible until the generator is normally started *For more details, please refer to the catalog. Feel free to contact us with any inquiries.

Outdoor Lithium-ion Battery Uninterruptible Power Supply 'LioUPS3'

Outdoor Lithium-ion Battery Uninterruptible Power Supply 'LioUPS3'

5G antennas will be installed on approximately 210,000 traffic lights nationwide. They will support traffic lights and antenna base stations as emergency power sources during power outages.

The "LioUPS3" is an outdoor uninterruptible power supply that achieves a wide operating temperature range and long lifespan by adopting high-performance lithium-ion batteries. Of the approximately 210,000 traffic signals maintained, operated, and managed by prefectural police, it is said that about 30% are connected to the network (as of summer 2019). There is an increasing expectation for the expansion of centralized control areas for traffic signals using 5G, aiming for safer and smoother traffic in anticipation of a self-driving society. 5G, characterized by high speed, large capacity, ultra-low latency, and numerous simultaneous connections, is expected to begin partial operation in 2020 as its deployment starts. Since 5G uses higher frequencies than before, a denser installation of base stations will be necessary. For these reasons, the construction of a 5G network utilizing traffic signals is about to begin. In recent years, power outages caused by natural disasters such as typhoons, heavy rain, and earthquakes have led to traffic signals losing power and antenna base stations going offline, affecting social life by disrupting mobile phones and smartphones. In such times, Seiwa Electric's outdoor uninterruptible power supply is essential. *For more details, please refer to the materials. Feel free to contact us with any inquiries.
