Description
Super economy control operation (S-ECO)
is a working mode that combines the
combines the advantages of high
efficiency in ECO mode and high
reliability in normal mode. In S-ECO
mode, the UPS preferentially supplies
power to loads directly through the
bypass and automatically determines
whether to compensate for load
harmonics based on load conditions to
achieve higher efficiency. It ensures
uninterruptible (0 ms) power supply and
reduces the impact of load harmonics on
the power grid.
NOTE
● Only the three-phase four-wire 380 V
AC/400 V AC/415 V AC (line voltage)
model supports the S-ECO mode.
● The system can work in S-ECO mode only
when the hardware of both the power
module and bypass module supports the
S-ECO mode.
● If the hardware of the existing power
module or bypass module does not
support the S-ECO mode, the ECO mode is
displayed (2–5 ms interruption may occur
during the transfer of this traditional ECO
mode). If the UPS works in S-ECO mode
but the hardware of the power module or
bypass module is changed and does not
support the S-ECO mode, a dialog box is
displayed, indicating that the hardware
does not support the S-ECO mode. After
you click OK, the UPS works in ECO mode.
The ECO mode is an economical working
mode and needs to be manually set. In
ECO mode, when the bypass input is
within the ECO voltage and frequency
ranges and other ECO power supply
conditions are met, the UPS works in
bypass mode and the inverter is in
standby state. When the bypass source
voltage is outside the ECO voltage range,
the UPS transfers from bypass mode to
inverter mode. In either bypass mode or
inverter mode, the rectifier is started all
the time and charges batteries using
DC/DC. The ECO mode delivers a high
efficiency.
