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 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 param-
eter 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
: If the UPS is set to CVCF mode, the bypass function will be disabled automatically.
But when a single UPS is powered on with mains and before the UPS has finished the
startup, there will be a few seconds of voltage pulse (same as the input voltage) on the bypass output.
If you need to remove the pulse on this mode to protect your load better, you could contact the dealer
for help.
