Uninterruptible Power Supply [Reducing the risk of material loss during disasters!]

Supply power during unexpected blackouts in emergencies! Prevent loss of components due to forced shutdowns and reduce risks.

In the event of power outages caused by disasters, lightning strikes, or snow damage, forced shutdowns can lead not only to damage to computer systems but also, in the worst-case scenario, to the potential loss of data. The uninterruptible power supply 'KE-0520 series' is a device designed to protect equipment from various troubles. During a power outage, it continues to supply power to the equipment, thereby reducing the risk of component loss due to forced shutdowns. Additionally, it is possible to implement targeted measures against momentary power outages by introducing it only to critical machinery and equipment rather than the entire factory. 【Features】 ■ Suitable for momentary power outage measures for industrial machinery and medical devices ■ Avoids risks of loss in materials, labor costs, and production through power backup ■ Two types of energy storage devices are available: "EDLC" and "lithium-ion batteries" ■ Assistance is also possible until the generator is normally started *For more details, please refer to the catalog. Feel free to contact us with any inquiries.

Uninterruptible power supply that can be installed when traffic lights go out due to a power outage.

A UPS (Uninterruptible Power Supply) that carries a mochi to restore power when a power outage occurs and the traffic signals go out.

In urban areas such as large cities, power outages can occur due to various troubles. When a power outage happens, traffic signals for vehicles and pedestrians installed on the roads go dark, causing the traffic network to become paralyzed. Although police officers will manage traffic, the time until restoration cannot be predicted. In such situations, the portable and outdoor-installable uninterruptible power supply LioUPS3 comes into play. Normally, it is kept as a backup power source for other devices, and in the event of a power outage caused by natural disasters such as earthquakes, typhoons, heavy rain, or electrical equipment troubles, the uninterruptible power supply can be transported by car and installed to restore power to the traffic signals, allowing them to operate temporarily. Additionally, Seiwa Electric aims to contribute to society based on two categories with the goal of "disaster reduction." Category 1: Providing rapid and accurate evacuation guidance during disasters. Category 2: Providing backup power sources during disasters. Seiwa Electric's uninterruptible power supply prevents system downtime during disasters and planned power outages.

Uninterruptible power supply for measures against natural disaster risks (typhoons, heavy rain, earthquakes, etc.)

Recently, Japan has been struck by major natural disasters (typhoons, heavy rain, earthquakes, etc.). As a countermeasure against the risk of power outages, portable uninterruptible power supplies are being utilized.

Recently, Japan has been struck by significant natural disasters (such as typhoons, heavy rains, and earthquakes). The large earthquake with a seismic intensity of 7 that hit Hokkaido in September 2018 (the Hokkaido Eastern Iburi Earthquake) caused a massive blackout across the entire region due to a loss of power supply, which is still fresh in our memories. Additionally, the anticipated occurrence of the Nankai Trough earthquake, a Tokyo metropolitan area earthquake, and abnormal weather due to global warming cast a shadow of anxiety over our lives. In such times, the portable, uninterruptible power supply LioUPS3, which can be set up and operated in outdoor environments, plays a vital role. Typically, it is kept as a backup power source for other devices, and in the event of a power outage caused by natural disasters such as earthquakes, typhoons, heavy rains, or electrical equipment troubles, it can be transported by car to the desired location to restore power and can be temporarily operated. Seiwa Electric aims to contribute to society with the goal of "disaster reduction" based on two categories: Category 1: Providing rapid and accurate evacuation guidance during disasters. Category 2: Providing backup power sources during disasters.
