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 can be gained in the HE mode. Once mains supply is lost or abnormal
the UPS will transfer to Line mode or Battery mode and the load supported from
battery power.
Fig. 5-7 HE mode
The function could be enabled through the LCD setting or management
software (WinPower, etc.).
The transfer time of the output from HE mode to battery mode is less than
10ms, this however can still be too long for some sensitive electrical
equipment.
5.2.6 Converter mode
In converter mode the UPS will operate with a fixed output frequency (50Hz or
60Hz). Once the mains supply is lost or abnormal the UPS will transfer to
battery mode and the load is supplied from battery power.
