Uninterruptible power supply for responding to power outages caused by instantaneous voltage drops.

Uninterruptible power supply for responding to power outages caused by instantaneous voltage drops.

A power outage may occur due to a momentary drop in voltage. It is possible to restore power to the equipment you want to recover by transporting it.

In urban areas such as large cities, power outages can occur due to various troubles that cause a sudden drop in voltage. When a power outage happens, traffic lights for vehicles and pedestrians installed on the roads go out, paralyzing the traffic network. Although police officers manage traffic, the time required for restoration cannot be predicted. In such situations, the portable uninterruptible power supply LioUPS3, which can be set up and operated in outdoor environments, plays a vital role. Normally, it is kept as a backup power source for other devices, and in the event of a power outage caused by natural disasters like earthquakes, typhoons, heavy rain, or electrical equipment troubles, it can be transported by car to the traffic lights that need to be restored, providing power and allowing them to operate temporarily as traffic signals. 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.)

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.

[Case Study] Takanosu Golf Club

[Case Study] Takanosu Golf Club

Due to a power outage, we were unable to conduct settlement operations and had to respond manually! The goal is to ensure the safety and smooth guidance of our customers.

We would like to introduce a case study of the introduction of "Personal Energy Portable" at the Takano Su Golf Club, one of the most prestigious courses in Hiroshima Prefecture. The company experienced a sudden long-term power outage, resulting in a long line of customers waiting for checkout at the front desk. Servers, computers, and network equipment became unusable, and all functions necessary for the checkout process had to be performed manually. Through a recommendation from the integrator that supplied the golf management system, they selected our product, which allows for continuous use of the system for over two hours during a power outage. After its implementation, they were able to maintain continuous business operations even during outages. [Challenges] ■ Experienced a sudden long-term power outage ■ A long line of customers waiting for checkout formed at the front desk ■ All functions necessary for the checkout process had to be performed manually *For more details, please download the PDF or feel free to contact us.
