When the input voltage is within the
acceptable range, the UPS will provide
pure and stable AC power to output. The
UPS will also charge the battery in
online mode.
Energy saving mode:
When the input voltage is within voltage
regulation range, the UPS will bypass
voltage to output for energy saving.
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 the battery in this
mode.
When the input voltage is beyond the
acceptable range or there is a power
failure and the alarm sounds every 4
seconds, the UPS will backup power
from battery.
When input voltage is within the
acceptable range but UPS is in
overload, the UPS will enter bypass
mode or bypass mode can be set on the
front panel. The alarm sounds every 10
seconds.
The UPS is shut down and there is no
output supply power, but the batteries
may still be charged.
