1. Product introduction
1.1 Functions description
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”.

1.2 Mode description
Bypass mode
Bypass mode means that the UPS provides the power through the
internal bypass way to load directly without any regulation. If the
controller detects the mains is abnormal, it will shut off the output to
protect the load. The bypass voltage/frequency range and default
output status (on/off) could be set by communication software.
Line mode
Line mode means that the mains input is rectified/converted by the
AC/DC section and then inverted to stable output by DC/AC section.
In line mode, the output is clean and good to the loads. If the mains
get abnormal, the UPS will transfer to battery mode without interrupt.
Battery mode
Battery mode means that the battery power goes through the DC/DC
section to the inverter (DC/AC) and get a stable backup output when
the mains input is not usable. If the mains input recovered, the UPS
will transfer to line mode without interrupt.
Battery test mode
In this mode, the UPS will stop the AC/DC section and discharge the
battery while mains input is normal. If the controller found the battery
is error, it will transfer back to line mode immediately, and warning by
display to see whether the battery needs to be replaced. The battery
test mode could be trigged in line mode by pressing the button or by
the communication command.
Fault mode
If the UPS generates some internal failure and have to stop its
inverter, it will go into fault mode and alarm by display and buzzer.
In fault mode, the loads have the risk of power loss because the
output will come from the bypass after UPS fault.

Inverter status
LED
If it is turned on constantly, it shows
that the load current is supplied from
utility power or battery via the inverter.
If it is turned on constantly, it shows
that the UPS is in battery mode, and
the load current is from battery via the
inverter.

Orange
Bypass/Battery
mode LED
If it is flashing, it shows that the UPS
is in bypass mode, and the load
current is directly from the utility
power.
If it is turned on constantly, it shows
that the UPS is in fault mode;
6 Red
Fault/Warning
mode LED
If it is flashing, it shows that the UPS
is in warning status.

1.3.3 Button
There is only one button for ON/OFF/Mute function on this product.
The controller can distinguish the command according to the
operation time difference.
1) Button action description
Button actions are distinguished with “short-press” and “long-press”.
Please refer to the following tables for the detail.
Button action type Definition
Short-press Press the button more than 0.04s and less than 0.5s
Long-press Press the button more than 2s
Invalid press Press the button more than 0.5s and less than 2s.
