SANYO DENKI Develops Highly Reliable SANUPS A22A Online UPS
3-phase 4-wire 400 VAC type with an output capacity of 5 kVA to 105 kVA


August 7, 2018

SANYO DENKI CO., LTD. has developed the highly reliable SANUPS A22A online UPS. It is suitable for use in Asia and Europe due to its 3-phase 4-wire 400 VAC specifications. A wide range of output capacities from 5 to 105 kVA can be selected. Even during power outages or voltage dips, power can be supplied without interruption.



1. Industry’s Highest Efficiency(1)

  • The SANUPS A22A achieves high efficiency levels of up to 94.5%. This reduces running costs and contributes to energy savings.

2. Flexible System Configuration

  • 5 kVA modules allow users to select the output capacity to match the needs of the application.
  • By combining optional external battery modules, backup time during power outages can be extended.

3. High Reliability

  • The double conversion online topology ensures continuous supply of stable high quality power.
  • Parallel redundant operation further improves reliability of the power supply.

4. Wide Input Range

  • With a wide input voltage range of 240 to 460 V(2) and a wide input frequency range of 46 to 54 Hz,(3) the SANUPS A22A can deal with unstable power sources. This prevents unnecessary battery operation, minimizing battery drain.

5. Easy Maintenance

  • Front-access design allows users to install and remove battery and inverter modules easily.
  • Maintenance can be performed without interrupting the inverter power to critical loads during parallel redundant operation. In addition, power can continue to be supplied even if an outage occurs during maintenance.
