SANYO DENKI Develops Parallel Redundant UPS SANUPS A11N-Li with Long-Life Lithium-Ion Battery

September 14, 2023

SANYO DENKI CO., LTD. has developed and launched the highly efficient SANUPS A11N-Li parallel redundant double conversion online UPS with lithium-ion battery. Among UPSs with equivalent specifications, this is the first in the industry to use lithium-ion batteries.(1)


10 kVA


1. Long Service Life

The UPS uses lithium-ion batteries. It can operate for 10 years without battery replacement,(2) reducing the maintenance work and costs.

2. Space-Saving and Lightweight

The compact 3U-sized(1) UPS unit is suitable for standard EIA/JIS 19-inch racks. The mass and volume have been reduced by up to 42% and 25%, respectively, compared to our current product.(3)

3. High Reliability

By combining up to four 5 kVA UPS units, output capacity can be expanded to up to 20 kVA or up to 15 kVA for parallel redundant operation. The parallel redundant operation allows one unit to be used as a spare unit, delivering a highly reliable and stable power supply to loads. In addition, this UPS performs battery self-tests automatically at regular intervals, preventing malfunction due to battery run-out in the event of a power failure.

4. High Efficiency

This UPS achieves a conversion efficiency of 94% or greater (up to 95.1%).(1)

5. For Use as an Emergency Battery

This UPS features battery cold start function(4) that enables the UPS unit to start up and power loads from the battery even without grid AC power.

(1) In a 5 kVA configuration with a single unit.

(2) Assuming 10 power outages per year and an ambient temperature of 30°C.

(3) Current product: SANUPS A11N (with lead-acid batteries, single unit, 5 kVA output capacity, backup time of 10 minutes)

(4) This function is selectable at the time of order.
