Uninterruptible Power Supply (UPS)

Uninterruptible Power Supply (UPS)

It is a device that supplies power to PCs and other equipment during power outages or electrical failures, allowing for business continuity or providing time for a safe shutdown.

In today's logistics warehouses, where digitalization and automation have advanced, power supply troubles can potentially cause catastrophic damage. To minimize the risks of disasters and power outages, the implementation of power protection solutions is essential. APC has achieved the number one industry share in UPS sales. Numerous APC brand products have been introduced in server rooms and IT equipment, which always require a stable power supply.

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 important infrastructure. Seiwa Electric's lithium-ion battery-based power outage countermeasures: Uninterruptible power supply.

All-weather Lithium-ion Battery Uninterruptible Power Supply LioUPS3 The road network along the Tohoku coast, which had been disrupted, has nearly been restored. Seiwa Electric is developing disaster reduction urban planning 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 disaster risks 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 inability to see can trigger panic. Securing a light source alone can provide reassurance. Additionally, to prepare for the anticipated Nankai Trough earthquake, it is urgent to install warning lights and evacuation guidance lights in the Kansai region during tsunami events. "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."

Emergency small power supply that can be activated solely by sunlight.

Emergency small power supply that can be activated solely by sunlight.

Active during emergencies such as disasters! A 'disaster prevention emergency power supply' that can operate independently using solar power even when commercial power is stopped.

Even if solar power is introduced, it cannot be called a disaster prevention measure if it cannot be used in emergencies. Nisshin Electric's emergency power supply is a self-sufficient system that can be activated solely by solar power. It can start autonomous operation even when it is difficult to receive power from the grid. Additionally, by utilizing storage batteries, it can supply electricity even at night. It is a power source for "disaster prevention." 【Features】 ■ Can autonomously start up using only solar power, ensuring peace of mind during long-term power outages ■ Equipped with an inverter that allows for both storing and using power in one unit ■ Four operating modes to choose from based on application *For more details, please download the catalog or contact us.

"Solar Independent Power Supply System" - Case study available (River Monitoring)

"Solar Independent Power Supply System" - Case study available (River Monitoring)

Due to its independent design, it excels in places where securing power is difficult! It's reassuring because you can use electricity even during disasters or power outages!

During the day (when there is sunlight), the power generated by the solar panels is supplied to the devices, while at night (when there is no 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 various 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 like parks or 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 a variety of applications depending on your ideas ★ For more details, please download the catalog or specifications, or contact us.

Uninterruptible Power Supply (UPS)

Uninterruptible Power Supply (UPS)

Backup important devices even during a power outage!

In recent years, disasters centered around typhoons and heavy rain have been increasing. Outdoor surveillance cameras, such as river monitoring cameras, are very convenient for information transmission in such situations, but if the commercial power supply goes out, 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 provides power to the equipment but also charges the built-in battery. During commercial power outages due to disasters, power can be supplied to the equipment from the built-in battery for a certain period of time, making it effective for backing up important devices. The casing is made of stainless steel, which is ideal for permanent outdoor installation, making it durable and reliable. This device uses a constant inverter power supply method that switches without interruption, and it provides output voltages of AC 100V and DC 12V, allowing it to be used for backup of various outdoor permanent devices such as communication equipment. With an output capacity of 30VA and 30W, it is recommended for backing up relatively low-power cameras, sensors, and measuring instruments.
