Disaster reduction and national resilience measures: Responding to power outages caused by disasters to deliver safety and security.

Disaster reduction and national resilience measures: Responding to power outages caused by disasters to deliver safety and security.

Disaster prevention and mitigation, national resilience measures - Emergency measures for strengthening critical infrastructure. Seiwa Electric's lithium-ion battery-based power outage measures - Uninterruptible power supply system.

All-weather Lithium-ion Battery Uninterruptible Power Supply LioUPS3 The road network along the Tohoku coast, which had been disrupted, has almost been restored. Seiwa Electric is developing disaster reduction urban development products, including road information displays and road and tunnel lighting that support logistics and the movement of people. "It is difficult to predict and prevent disasters, and disaster reduction, which minimizes the risk of disasters as much as possible, is becoming mainstream. Last year, there was a large-scale power outage, but evacuation guidance lights are essential in emergencies. To avoid situations where displays and lights cannot operate due to power outages, we are focusing on outdoor lithium-ion battery uninterruptible power supplies that are lightweight, long-lasting, and equipped with maintenance functions that self-diagnose battery deterioration." In emergencies, the situation of not being able to see can induce panic. Securing a light source alone can provide reassurance. Additionally, in preparation for the anticipated Nankai Trough earthquake, it is urgent to install warning lights and evacuation guidance lights in the Kansai region in the event of a tsunami. "We will continue to focus on disaster reduction measures nationwide. We must provide products that minimize damage when disasters occur. Moving forward, we want to deliver safety and security in ways that are not visible to everyone."

Peace of mind knowing you can use electricity even during disasters and power outages!

Peace of mind knowing you can use electricity even during disasters and power outages!

It is an independent power supply system that combines solar panels and batteries. Therefore, it can supply electricity even during disasters and power outages!

The "Solar Independent Power Supply" is a self-sufficient power system that utilizes solar panels and batteries. During the day (when there is sunlight), the power generated by the solar panels is supplied to devices, and any surplus electricity is charged into the built-in battery. At night (when there is no sunlight), the power stored in the battery is supplied to the devices. Therefore, it serves as a new power source for installing surveillance cameras and LED lighting in areas where securing electricity is difficult, such as riverbanks, mountainous regions, and vast parks! It can be used for a variety of applications, but it is particularly recommended for supplying power to devices with relatively low power consumption, such as surveillance cameras, LED lighting, and sensors! As it is a "clean energy" source that does not emit carbon dioxide and other substances considered to contribute to global warming, its utilization is expected to increase in the future. ◇ A power source for locations where it is difficult to connect to commercial power due to construction costs or landscape considerations ◇ Uses a stainless steel housing suitable for outdoor installation ◇ Completely independent, so no electricity costs are required ★ For more details, please download the catalog and specifications or contact us.

"Solar Independent Power Supply System" - Case Study Available (River Monitoring)

As an independent type, it excels in places where securing power is difficult! It's reassuring because you can use electricity even during disasters and power outages!

During the day (with sunlight), the power generated by the solar panels is supplied to the devices, while at night (without sunlight), the power stored in the battery is used. Additionally, even during long periods of no sunlight, such as during the rainy season, it can operate for about 72 hours! (When using one battery with a load of 4W) It can be used for a variety of purposes, but it is recommended for powering low-consumption devices such as surveillance cameras, LED lighting, and communication devices like Wi-Fi! 《Features》 ● Ideal for cases where wiring is difficult in vast areas such as parks and mountainous regions ● Power supply is possible even during power outages ● We propose a set of power supply unit and solar panels ● Simple installation work due to its independent power supply type ● Can be used for various purposes depending on your ideas ★ For more details, please download the catalog and specifications or contact us.

Uninterruptible Power Supply (UPS)

Uninterruptible Power Supply (UPS)

Backup important equipment even during a power outage!

In recent years, disasters centered around typhoons and heavy rain have been increasing. Outdoor surveillance cameras, such as those installed for monitoring rivers, are very convenient for information transmission in such situations, but if the commercial power supply goes down, the information from the cameras will also stop. By using an uninterruptible power supply (UPS) for backup during unexpected power outages, it is possible to prevent such situations. When commercial AC 100V power is supplied, it not only powers the equipment but also charges the built-in battery. During commercial power outages due to disasters, the built-in battery can supply power to the equipment for a certain period, making it useful for backing up important devices. The casing is made of stainless steel, making it durable and reliable for permanent outdoor installation. This device uses a constant inverter power supply method that allows for seamless switching, and it provides output voltages of AC 100V and DC 12V, making it suitable for backing up various outdoor equipment such as communication devices. With an output capacity of 30VA and 30W, it is recommended for backing up relatively low-power cameras, sensors, and measuring instruments.
