5.2.5 HE mode (High Efficiency

mode)

It is also called economy mode.

After the UPS is turned on, the power used by the load is supplied

from the mains power via internal filter while the mains power is in

normal range, so the high efficiency could be gained in the HE mode.

Once the mains power is loss or abnormal, the UPS would transfer

to Line mode or Battery mode and the load is supplied continuously.
