5.2.5 HE mode (High Efficiency
mode
)
It is also called economy (ECO) mode.
After the UPS is turned on, the power used by the load is supplied from the
utility power via internal filter while the utility power is in normal range, so the
high efficiency could be gained in the HE mode. Once the mains is loss or
abnormal, the UPS would transfer to Line mode or Battery mode and the load
is supplied continuously.
