6.5 EPO (Emergency Power Off)
It is also called RPO (Remote Power Off). On LCD display, the word of
“
EPO
”
will be presented in the position of output voltage.
It is a special status which the UPS will shut the output off and send out
alarm. The UPS cannot be turned off by pressing
“
OFF
”
button on the
panel, only after resetting EPO status.
6.6 ECO mode (Economy mode)
It is also called high efficiency mode. After turning UPS on in ECO mode,
the output power will be supplied from mains power directly via internal
filter while the mains power is in certain range, so the high efficiency
performance would be gained in ECO mode. Once the mains power is
loss or out of range, the UPS will transfer to battery mode and the load
will be supplied continuously by the battery.
1) ECO mode can be enabled through the LCD setting or the software
(Winpower, etc.).
2) The transfer time of UPS output from ECO mode to battery mode is
less than 10ms. It is suggested that takes account of application for
some sensitive load.
6.7 CVCF mode
CVCF (Constant Voltage Constant Frequency) which is also called
converter mode, UPS would works in frequency free-run with fixed
output frequency (50Hz or 60Hz). Once the mains are loss or abnormal,
the UPS would transfer to battery mode and the load is supplied
continuously by the battery.
1) CVCF mode can be enabled through the LCD setting or the software
(Winpower, etc.).
2) The normal power rating will be derating to 60% in converter mode.
