8. 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.
8.1. ECO Function
Brief introduction of ECO function
：
If ECO function is set to enable, after the UPS is turned on, the power used by the
load is directly supplied from the mains power via internal filter while the utility
power is in normal range, so the economy mode could be gained in ECO 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.
The great virt

But the disadvantage is:
1) The load can
’t be protected as well as in Line mode, for the load is directly
supplied from the mains;
2) The transfer time of UPS output from ECO mode to Battery mode is about
10ms.
So the function is not suitable to some sensitive loads, and the region where the
mains power is unstable.

The function could be enabled through the LCD setting in Bypass mode. Enter the
power strategy setting menu by following chapter of 7.3.
8.2. Converter Function
Brief introduction of Converter function

Battery mode and the load is supplied continuously.

sensitive loads. But the disadvantage is the load capacity of UPS should be
derated to 60% in converter mode.
