02: Output frequency
Interface Seng
60 Hz, CVCF mode
50 Hz, Normal mode
ATO
Parameter 2: Output Frequency
Seng the output frequency. You may choose following three opons in
parameter 2:
50.0Hz: The output frequency is seng for 50.0Hz.
60.0Hz: The output frequency is seng for 60.0Hz.
ATO: If selected, output frequency will be decided according to the latest
normal ulity 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 seng.
Parameter 3: Frequency mode
Seng output frequency at CVCF mode or not CVCF mode. You may
choose following two opons in parameter 3:
CF: Seng UPS to CVCF mode. If selected, the output frequency will be
xed at 50Hz or 60Hz according to seng in parameter 2. The input fre-
quency could be from 46Hz to 64Hz.
NCF: Seng UPS to normal mode (not CVCF mode). If selected, the out-
put frequency will synchronize with the input frequency within 46~54 Hz
at 50Hz or within 56~64 Hz at 60Hz according to seng in parameter 2.
If 50 Hz selected in parameter 2, UPS will transfer to baery mode when
input frequency is not within 46~54 Hz. If 60Hz selected in parameter
2, UPS will transfer to baery 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 funcon will be disabled automacally.
But when a single UPS is powered on with mains and before the UPS nished 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 beer, you could contact the dealer
for help.
03: Voltage range for bypass
Interface Seng
Parameter 2: Set the acceptable low voltage for bypass. Seng range is
from 110V to 209V and the default value is 110V.
Parameter 3: Set the acceptable high voltage for bypass. Seng range is
from 231V to 276V and the default value is 264V.
