Parallel redundant double conversion online UPS with high efficiency.



High Efficiency

This UPS achieves a conversion efficiency of 94% (up to 95.1%).(3)

High Reliability

Output capacity can be expanded to up to 20 kVA by combining up to four 5 kVA units. The parallel redundant operation allows one unit to be used as a spare unit, delivering a highly reliable and stable power supply to loads.

The UPS performs battery self-tests automatically at regular intervals, preventing malfunction due to battery run-out in the event of a power failure. Battery testing requires no power interruption to loads.
