Description
When the input voltage is within
acceptable range, UPS will provide pure
and stable AC power to output. The UPS
will also charge the battery at online
mode.
Energy saving mode:
When the input voltage is within voltage
regulation range, 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 battery under this
mode.
When the input voltage is beyond the
acceptable range or power failure and
alarm is sounding every 4 second, UPS
will backup power from battery.
