SANUPS E23A/E33A - Parallel Processing (UPS)

SANUPS E23A/E33A
Highly reliable and efficient parallel processing UPS
This UPS utilizes a parallel processing topology to securely backup power during power outages, dips, interruptions and other electrical disturbances.
In addition to resisting the adverse effects of inrush currents, this UPS can effectively eliminate harmful harmonic currents while supplying high quality
and reliable electricity to ensure stable operation of factory facilities.

Highly Efficient Parallel Processing Topology
The SANUPS E23A and E33A use a parallel processing topology which feeds grid power to the load while a bi-directional inverter connected in parallel
controls voltage and absorbs noise. Even during power outages, instantaneous voltage dips, and momentary outages, the inverter provides uninterrupted
pure sine waves for safe, stable power supply.
What’s more, with an excellent conversion efficiency of 98%, these UPSs help cut energy consumption to save utility bills. Configurations with backup times
up to 180 minutes can be selected.

Confident System Management with Periodic Self-Tests
Battery self-tests can be performed automatically at regular intervals, ensuring reliable operation in the event of a power failure. These battery self-tests are
done directly from the grid so there is no effect on the UPS even if the battery has degraded.

Correction for Harmonic Distortion and Power Factor
An active filter includes a bi-directional inverter that cancels the harmonics generated by the equipment, making the source current sinusoidal and harmless
to other equipment and the grid. Furthermore, the UPS power factor can be corrected to nearly 1.0.

Scalable Capacity 
To meet power demands, capacity can be expanded by adding 100 kVA units.
The UPS system can be expanded up to 600 kVA.
