Industry’s widest operating temperature range

April 10, 2018

SANYO DENKI CO., LTD. has developed the SANUPS N11C-Li standby UPSs equipped with lithium-ion batteries.
These UPSs have the widest operating temperature range in the industry,(1) ensuring stable operation even in extreme temperatures.
They are suitable for use in outdoor equipment cabinets, freight containers, emergency monitoring systems, and indoor facilities without air conditioning.



1. Widest Operating Temperature Range in the Industry(1)

The operating temperature range is from -20 to +55°C, which is the widest in the industry.
This ensures a carefree operation even in harsh cold or hot environments.

2. Long Service Life

These UPSs are equipped with lithium-ion batteries, providing approximately twice the service life of our conventional lead-acid battery-equipped UPS.(2)
This eliminates the need for battery replacement for 10 years,(3) reducing maintenance work and costs.

3. Space Saving

The volume is approximately half that of our conventional UPS,(2) enabling installation in smaller spaces.

4. High Efficiency

A 95% efficiency has been achieved, contributing to energy savings.

Note: This product is designed for use in Japan.

(1) Based on our own research as of April 10, 2018, among standby UPSs on the market with equivalent voltage and capacity.

(2) Our conventional UPS: A11K (with lead-acid batteries).

(3) Assuming 10 power outages per year and 30°C ambient temperature.
