Description
Super economy control operation (S-ECO) is a
working mode that combines the economy
control operation (ECO) mode and inverter
mode and needs to be manually set. The UPS
supplies power to loads preferably 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 a charger. The ECO mode
delivers a high efficiency.
