The UPS has powered off output power, but the battery can still be charged.

Line Mode

When the input voltage/frequency are within acceptable range, the UPS will provide pure and stable AC power to output. The UPS will also charge the battery under this mode.

Battery Mode

When the input voltage is beyond the acceptable range or as a consequence of a power failure, UPS will backup power from battery.

ECO Mode

(Efficiency Corrective Optimizer) When the input voltage/frequency are within acceptable range, the UPS will bypass voltage to output for energy saving. PFC and INVERTER are still active at this mode.

Advanced ECO Mode

(Advanced Efficiency Corrective Optimizer) When the input voltage/frequency are within acceptable range, the UPS will bypass voltage to output for energy saving. PFC and INVERTER are off at this mode.

Bypass Mode

When input voltage/frequency are within acceptable range but UPS is overload, the UPS will enter Bypass Mode or Bypass Mode can be set by front panel or you can set the UPS to enter Bypass Mode when the UPS is off: the UPS will bypass voltage to output.

Converter Mode

(Frequency Converter Mode) When input frequency is within 40 Hz to 70 Hz, the UPS can be set at a constant output frequency, 50 Hz or 60 Hz. The UPS will still charge battery under this mode.

Battery Test Mode

The UPS is performing a battery test.

Fault Mode

The UPS is in Fault Mode when a fault is found and no output power is supplied by the UPS.

AVR Mode

The UPS bypasses voltage to output regulating input voltage to the appropriate level.
