02: Output frequency
Interface Setting
60 Hz, CVCF mode
50 Hz, Normal mode
ATO
Parameter 2: Output Frequency
Setting the output frequency. You may choose following three
options in parameter 2:
50.0Hz:
The output frequency is setting for 50.0Hz.
60.0Hz:
The output frequency is setting for 60.0Hz.
ATO:
If selected, output frequency will be decided according to the
latest normal utility frequency. If it is from 46Hz to 54Hz, the output
frequency will be 50.0Hz. If it is from 56Hz to 64Hz, the output
frequency will be 60.0Hz. ATO is default setting.
Parameter 3: Frequency mode
Setting output frequency at CVCF mode or not CVCF mode. You
may choose following two options in parameter 3:
CF:
Setting UPS to CVCF mode. If selected, the output frequency will
be fixed at 50Hz or 60Hz according to setting in parameter 2. The
input frequency could be from 46Hz to 64Hz.
NCF:
Setting UPS to normal mode (not CVCF mode). If selected, the
output frequency will synchronize with the input frequency within
46~54 Hz at 50Hz or within 56~64 Hz at 60Hz according to setting in
parameter 2. If 50 Hz selected in parameter 2, UPS will transfer to
battery mode when input frequency is not within 46~54 Hz. If 60Hz
selected in parameter 2, UPS will transfer to battery mode when input
frequency is not within 56~64 Hz.
*If Parameter 2 is ATO, the Parameter 3 will show the current
frequency.
Note: For single unit, it will have bypass output for a couple of seconds after the unit is powered on.
Therefore, to avoid damage on connected devices, it is strongly suggested to add an additional
Output relay board for CVCF application.
z
03: Voltage range for bypass
Interface Setting
Parameter 2:
Set the acceptable low voltage for bypass. Setting
range is from 110V to 209V and the default value is 110V.
Parameter 3:
Set the acceptable high voltage for bypass. Setting
range is from 231V to 276V and the default value is 264V.
04: Frequency range for bypass
Interface Setting
Parameter 2:
Set the acceptable low frequency for bypass.
50 Hz system: Setting range is from 46.0Hz to 49.0Hz.
60 Hz system: Setting range is from 56.0Hz to 59.0Hz.
The default value is 46.0Hz/56.0Hz.
Parameter 3:
Set the acceptable high frequency for bypass.
50 Hz: Setting range is from 51.0Hz to 54.0 Hz.
60 Hz: Setting range is from 61.0Hz to 64.0Hz.
The default value is 54.0Hz/64.0Hz.
z
05: ECO mode enable/disable
Interface Setting
Parameter 3:
Enable or disable ECO function. You may choose
following two options:
DIS:
disable ECO function
ENA:
enable ECO function
If ECO function is disabled, voltage range and frequency range for
ECO mode still can be set, but it is meaningless unless the ECO
function is enabled.
