Uninterruptible Power Supply
• Output Voltage: Select the output rated voltage.
There are two options, 120V and 127V. 120Vac is default setting.
• Output Rated FRE: Select output rated frequency.
50Hz: The output frequency is setting for 50Hz.
60Hz: The output frequency is setting for 60Hz. 60Hz is the default setting.
• VCF Mode (constant voltage and constant frequency function)
Enable: CVCF function is enabled. The output frequency will be fixed at 50Hz or 60Hz according to setting
of “Output Freq.”. The input frequency could be from 40Hz to 70Hz.
Disable: CVCF function is disabled. The output frequency will synchronize with the bypass frequency
within 45~55 Hz for 50Hz system or within 55~65 Hz for 60Hz system. Disable is the default setting.
• Bypass Forbid:
Enable: Bypass Forbid is enabled. It’s not allowed for running in Bypass mode under any situations.
Disable: Bypass Forbid is disabled. UPS will run in Bypass mode. It is the default setting.

• Bypass at UPS off: Select the bypass status when manually turning off the UPS. This setting is only
available when “Bypass forbid” is set to “Disable”.
Enable: Bypass enabled. When selected, bypass mode is activated. Enable is the default setting.
Disable: Bypass disabled. When selected, no output through bypass when manually turning off the
UPS.
• Bypass Voltage Range: Set the bypass voltage range.
L: Low voltage point for bypass. The setting range is 96V ~ 110V. 96V is default setting.
H: High voltage point for bypass. The setting range is 130V ~ 146V. 146V is default setting.
• Bypass FRE Range: Set the bypass frequency range.
The acceptable bypass frequency range from 46Hz to 54Hz when UPS is 50Hz system and from 56Hz
to 64Hz when UPS is 60Hz system.
• ECO mode: Enable/Disable ECO mode. Default setting is “Disable”.
• ECO Voltage Range: Set the ECO voltage range.
L: Low voltage point for ECO mode. The setting range is from “Rated output voltage – 5V” to “Rated
output voltage - 11V”. “Rated output voltage – 5V” is default setting.
H: High voltage point for ECO mode. The setting range is from “Rated output v 5V” to
“Rated output v 11V”. “Rated output v 5V” is default setting.
• ECO FRE Range: Set the ECO frequency range. The setting range is from 48Hz to 52Hz when the UPS
is 50Hz system and from 58Hz to 62Hz when the UPS is 60Hz system.
