Emergency self-generation power supply "Cute Power Series" *For BCP measures!

Basic materials for BCP measures are also being provided! A compact vertical type emergency generator capable of continuous operation for up to 72 hours.

In recent years, various companies have been working on BCP (Business Continuity Planning) measures. In Japan, where natural disasters such as earthquakes and heavy rains are frequent, it is uncertain when unexpected power outages or factory shutdowns may occur. The emergency generator system "Cute Power Series" is an all-in-one emergency generator that includes all the necessary equipment for power outage measures, such as an automatic start panel and power transfer switch, all packaged together. It has passed seismic tests equivalent to the Great East Japan Earthquake (Shindo 7 level), making it less likely for the generator unit to fail due to an earthquake. Some products in the series can operate continuously for up to 72 hours, making them suitable for BCP measures. Additionally, basic materials for BCP measures are also available. 【Features】 ■ Compact design with a large-capacity fuel tank ■ Salt damage specification with electrostatic painting ■ Quiet low-noise model ■ All-in-one structure ■ Automatic maintenance operation for peace of mind ■ Passed seismic tests equivalent to the Great East Japan Earthquake *For more details, please refer to the PDF materials or feel free to contact us.
