This product is a true online double-conversion UPS (Uninterruptible Power
Supply). It provides perfect protection for critical load such as computer system.
It can eliminate almost all mains power disturbances. The input AC current can
be corrected to a wave following the mains voltage, so it is a high power factor
system. Through the PWM control technology, the output voltage can be a pure
& stable sine wave AC voltage.
When the mains input become abnormal, the controller will stop the AC/DC and
start the DC/DC section immediately to make sure the DC/AC (inverter) section
can continue to work. After the mains input comeback to normal range, the
DC/DC will be stopped and the AC/DC works again. So the load is always
power-supplied through inverter without any interrupt if the UPS is turned on.
The UPS also provides an internal bypass way to make the load can be powered
by mains input directly when the UPS is off or failed.
The UPS have an internal charger for batteries, the charger will charge the
batteries when the mains is in a reasonable range on "bypass mode" or "line
mode".

2) Deactivate acoustic alarm: By pressing this Button, an
acoustic alarm can be deactivated in the battery mode.
3) Do the battery test: By pressing this Button, UPS can do
battery test in Line mode or ECO mode or Converter mode.
1) When mains power is normal, the UPS system switches
OFF-Button
to No output or Bypass mode by pressing this Button, and
the inverter is off. At this moment, if Bypass is enabled,
then the output are supplied with voltage via the bypass if
the mains power is available.
2) Deactivate acoustic alarm: By pressing this Button an
acoustic alarm can be deactivated in the bypass mode.
3) Release the UPS back to Bypass mode or no output
mode from fault mode and EPO status.
If the UPS system is No output or Bypass mode, the output
SELECT-Button
voltage, frequency, Bypass disable/enable and operating
mode, could be selected by pressing SELECT-Button, and
ENTER-Button
confirmed by pressing ENTER-Button
