4. Operation
01: Output voltage
Interface Setting
Parameter 3: Output voltage
You may choose the following output voltage in Parameter 3:
220: Output voltage is 220V AC.
230: Output voltage is 230V AC.
240: Output voltage is 240V AC.
02: Output frequency
Interface Setting
60Hz, Freq. Converter Mode
50Hz, Normal Mode
ATO
Parameter 2: Output Frequency
Set the output frequency. You may choose three options in Parameter 2:
50.0Hz: Output frequency is 50.0Hz.
60.0Hz: Output frequency is 60.0Hz.
ATO: If selected, output frequency will be decided according to the latest normal utility frequency. If
it is between 46Hz to 54Hz, the output frequency will be 50.0Hz. If it is between 56Hz to 64Hz, the
output frequency will be 60.0Hz. Automatic (ATO) is the default setting.
Parameter 3: Frequency Mode
Freq. Converter Mode has two options to choose from in Parameter 3:
CF: Set UPS to Freq. Converter Mode. If selected, the output frequency will be fixed at 50Hz or
60Hz according to the setting in Parameter 2. The input frequency can range from 46Hz to 64Hz.
NCF: Set UPS to Normal Mode (not Freq. Converter Mode). If selected, the output frequency will
synchronize with the input frequency within 46~54Hz at 50Hz or within 56~64Hz at 60Hz accord-
ing to the setting in Parameter 2. If 50Hz is selected in Parameter 2, the UPS will transfer to Battery
Mode when the input frequency is outside 46~54Hz. If 60Hz is selected in Parameter 2, the UPS
will transfer to Battery Mode when the input frequency is outside 56~64Hz.
*If Parameter 2 is ATO, Parameter 3 will show the current frequency.
Note: A single UPS unit will have bypass output for a couple of seconds after the unit is powered on. To avoid damage to connected devices, it is strongly
recommended to add an additional Output relay board for Freq. Converter application.
03: Voltage range for bypass
Interface Setting
Parameter 2: Set the acceptable low voltage for bypass. Setting range is from 110V to 209V.
The default value is 110V.
Parameter 3: Set the acceptable high voltage for bypass. Setting range is from 231V to 276V.
The default value is 264V.
04: Frequency range for bypass
Interface Setting
Parameter 2: Set the acceptable low frequency for bypass.
50Hz system: Setting range is from 46.0Hz to 49.0Hz.
60Hz 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.
50Hz: Setting range is from 51.0Hz to 54.0Hz.
60Hz: Setting range is from 61.0Hz to 64.0Hz.
The default value is 54.0Hz/64.0Hz.
