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.

is about 10ms. But it is still too long for some sensitive load.
