The outdoor-spec UPS "SANUPS N11B-Li" is suitable for cold regions, saves space, and is maintenance-free!

I want to create a surveillance camera system that can provide 24-hour backup in the event of a power outage.

K, a manufacturer of measuring equipment, manufactures and sells security and surveillance camera systems to government agencies and various corporations.
Recently, the company was consulted by a local government in which it had installed a surveillance camera system several years ago about long-term operation during power outages. Mr. N, manager of the R&D Technology Department at Company K, said:
"In recent years, there have been frequent unexpected large-scale natural disasters that have been designated as severe disasters. In response, local governments across the country are strengthening their efforts based on guidelines issued by government agencies for strengthening national resilience. This time, we were consulted about a system that could back up surveillance camera systems 24 hours a day in the event of a power outage caused by a disaster or other reason." (Mr. N)

Difficult to deal with with lead-acid battery type UPS

Mr. N began gathering information about Uninterruptible Power Supplies (UPS) for power backup.
"First, we looked for a UPS to back up the surveillance camera system, but we were told that 24-hour backup would not be possible unless we added additional lead-acid batteries. Surveillance camera systems are basically installed on utility poles, so a large UPS would be difficult to install. Moreover, lead-acid batteries generally have an expected lifespan of five years at an ambient temperature of 25°C, so regular maintenance is required.
In addition, the surveillance camera system we installed is also used to check the snow accumulation and icy conditions on roads in winter. Many of the UPS candidates had operating temperatures above 0°C, so we were concerned about their operation in snowy environments.
This time, we were planning to install it on a utility pole, so we had to select a UPS that could provide long-term backup, was small, and was suitable for outdoor use." (Mr. N)

Lithium-ion battery-equipped UPS provides 24-hour backup and space savings

Mr. N consulted SANYO DENKI CO., LTD. about these issues as the company had a track record of success in other departments and was therefore highly trusted.
The SANYO DENKI CO., LTD. representative listened to the details of the issues and later proposed the SANUPS N11B-Li.

"The UPS that was proposed to us is equipped with lithium-ion batteries, which are more compact than lead-acid batteries, so despite its small size it can provide backup for more than 24 hours. This model has been developed with mounting on utility poles in mind, and pole mounting brackets are also provided. This means it can be mounted on utility poles where surveillance cameras are installed. Another attractive feature is that lithium-ion batteries do not need to be replaced for 10 years, reducing the hassle of maintenance.
Furthermore, the protection rating is IP65, so it can be installed outdoors with peace of mind, and the operating temperature range is -20 to +50°C, so we decided it would operate satisfactorily in cold regions." (Mr. N)

Mr. N, who was very interested in this UPS, immediately began testing it within his company.
After verifying that SANUPS N11B-Li.
"We proposed a surveillance camera system to the customer in conjunction with SANYO DENKI CO., LTD. 's UPS, and the customer introduced it. We are relieved that we were able to fully meet the customer's requests, such as backup time and installation on utility poles. Furthermore, when the contractor actually carried out the installation on site, it was easy to install, so the work went smoothly. We would like to consult with SANYO DENKI CO., LTD. on various matters in the future." (Mr. N)
