Battery charger as AC-DC power supply!? 'NPP Series'

Battery charger as AC-DC power supply!? 'NPP Series'

It is a 2-in-1 designed device that allows the use of battery charger mode and power supply mode in a single unit.

Battery Charger "NPP Series" This product features two modes: battery charger mode and power supply mode. In battery charger mode, it performs excellently as a charger utilizing stage charging! However! In power supply mode, it is possible to charge the battery while also connecting a load to the unit, thereby providing a stable DC output! In the "3-stage charging" of the charger mode, it transitions from bulk charging to absorption charging and then to float charging. However, if a minimal load such as 5A is used, it may not transition to float charging and the charging will stop (it will not reach full charge). However, by using power supply mode, it allows for both full charging and stable supply to the load. Once the battery is fully charged, it will only supply the load stably. By disconnecting from the battery, it can also be used as an AC-DC power supply. For more details, please visit our website or view the catalog below.

Auxiliary power source in fuel cell vehicles

Auxiliary power source in fuel cell vehicles

Equipped with a high-output auxiliary battery! It is possible to combine the advantages of fuel cell vehicles and EVs.

Due to considerations for the SDGs and environmental issues, the transition from gasoline vehicles to environmentally friendly vehicles is rapidly progressing worldwide. However, there are concerns about resource shortages when it comes to fully electrifying vehicles using only lithium-ion batteries, which are currently mainstream in electric vehicles. Additionally, battery electric vehicles (BEVs) face the challenge of long charging times. On the other hand, fuel cell vehicles (FCVs), which generate power using hydrogen and oxygen to drive motors, are expected to be the cars of the future.

Auxiliary power source in fuel cell forklifts

Auxiliary power source in fuel cell forklifts

High-output auxiliary battery! Explanation of the features and technical advantages of lithium-ion capacitors (LIC).

The government has set a goal in its basic strategy for realizing a hydrogen society to promote the adoption of 10,000 fuel cell forklifts by 2030. Forklifts are essential transportation devices in manufacturing and logistics warehouses, with a global market size of approximately 1 million units per year. In Japan alone, there is a demand for about 10,000 units, and this demand is expected to increase further with the development of e-commerce. Traditionally, forklifts have been predominantly engine-driven, using gasoline and other fuels, but engine noise and exhaust emissions have become significant issues.

Emergency power supply that backs up the entire building for 6 hours before and after a power outage without interruption.

Emergency power supply that backs up the entire building for 6 hours before and after a power outage without interruption.

Introduced as a measure against unexpected power restoration accidents! Power supply to telephone and internet equipment can be sustained for about 10 hours.

We would like to introduce a case where the "Personal Energy Portable" was implemented in the Esca underground shopping district, which represents Nagoya. The company had to conduct a full building power outage for about six hours during the statutory electrical equipment inspection, which required coordination for personnel and phone responses, including transfers, due to the contractor's needs and the complete closure of the building during regular inspections. After the implementation, it became unnecessary to secure personnel and handle phone responses, including transfers, in line with the annual statutory electrical equipment inspection schedule. [Challenges] ■ For service industries with limited holidays, being cut off from external communication poses a significant risk. ■ During the legally mandated annual electrical equipment inspection, a power outage lasting several hours cannot be avoided. *For more details, please download the PDF or feel free to contact us.

A standalone power source combining solar panels and batteries!

A standalone power source combining solar panels and batteries!

It is an independent power supply that does not require commercial power, allowing for power supply even during disasters and power outages!

The "Solar Independent Power Supply" serves as a new power source in environments where securing outdoor electricity is difficult. During the day (when there is sunlight), it supplies power generated by solar panels to devices, and any surplus electricity is charged into the built-in battery. At night (when there is no sunlight), it supplies power stored in the battery to devices. Additionally, even during long periods without 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 applications, but it is particularly recommended for powering devices with relatively low power consumption, such as surveillance cameras, LED lighting, and communication devices like Wi-Fi. As it is a "clean energy" that does not emit carbon dioxide and other substances considered to be causes of global warming, it is also useful as educational materials in educational institutions and as a power supply during disasters or power outages! **Features** - Power supply is possible during disasters and power outages - Easy to install even in cases where wiring is difficult, such as in parks or mountainous areas - Power supply unit and solar panel are offered as a set - Environmentally friendly due to being clean energy - Can be used for a variety of applications depending on ideas! ★ For more details, please download the catalog and specifications or contact us.

[Case Study] Streamlining In-House Seismic Intensity Reporting and Accelerating Initial Response After an Earthquake

[Case Study] Streamlining In-House Seismic Intensity Reporting and Accelerating Initial Response After an Earthquake

Automation of situation reporting in IoT earthquake observation services enables rapid initial response.

**Overview** - **Purpose:** To streamline the situation reporting process during earthquakes - **Category:** IoT Earthquake Observation Service - **Related Products:** IoT Earthquake Observation Service - **Scope of Provision:** Complete set of equipment, implementation support, operational support, service provision **Background and Challenges** JFE Steel Corporation's East Japan Works (Chiba Area) covers an area of approximately 7.65 million m² (equivalent to about 165 Tokyo Domes) and employs around 11,000 people, including group and partner companies. In the Chiba area, multiple seismometers were installed throughout the factory to implement initial response measures as defined for each seismic intensity. However, traditional seismometers required manual data verification on-site, resulting in a reporting time of about 20 minutes. **Effects After Implementation** The verification of earthquakes on-site and the email reporting process have been automated, leading to improved operational efficiency. In particular, the time required for internal situation reporting has been reduced, enabling immediate responses to damage assessments, operational adjustments, and requests for support to other areas. Additionally, employees who were previously involved in this task can now focus on other responses immediately after an earthquake occurs.
