Uninterruptible Power Supply
01: Output voltage
Interface
Setting
Parameter 3: Output voltage
You may choose the following output voltage in parameter 3:
208
: Presents output voltage is 208Vac
220
: Presents output voltage is 220Vac
230
: Presents output voltage is 230Vac
240
: Presents output voltage is 240Vac
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 op-
tions 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 out-
put 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 fre-
quency.
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.
