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.
7.1 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 fil-
ter while the utility power is in normal range, so the economy mode could
be gained in ECO mode. Once the mains power is outsite the ECO voltage
range 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≥96% of UPS, to save power for
user.
But the disadvantage is:
1. The load can't be protected as well as in Line mode, when the
load is directly supplied from the mains;
2. The transfer time of UPS output from ECO mode to Battery mode is
about 10ms.
