6. Special function
The series UPS has some special functions, which could satisfy
some special application of user. And the functions have own
features, please contact your local distributor for further information
before using the function.
6.1 HE function
6.1.1 Brief introduction of HE function
If HE function is set to enable, after the UPS is turned on, the power
used by the load is directly supplied from the utility power via
internal filter while the utility power is in normal range, so the high
efficiency could be gained in HE mode. It is also called economy
mode. Once the mains is loss or abnormal, the UPS would transfer
to Line mode or Battery mode and the load is supplied continuously.
The great virtue is overall high efficiency >0.96 of UPS, to save
power for user.
But the disadvantage is 1) the load can not be protected as well as
in Line mode, for the load is directly supplied from the utility; 2) the
transfer time of UPS output from HE mode to Battery mode is about
10ms.
So the function is not suitable to some sensitive loads, and the
region where the utility power is unstable.
6.1.2 Set the function
The function could be enabled through the LCD setting in Bypass
mode.
Enter the power strategy setting menu by following chapter of 5.5.7.
