1. Product introduction
1.1 Function 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 waveAC 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 come back 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 path so that the load
can be powered by mains input directly when the UPS is off or
failed.
The UPS is equipped with an internal charger for batteries which
charges the batteries when the mains are within a reasonable
range under “bypass mode” or “line mode”.

1.4 Mode description
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 well-regulated and good to the loads. If
the mains get abnormal, the UPS will transfer to battery mode
without interruption.
In line mode, Line LED and Inverter LED are turned on constantly.
1. If Line LED flashes, it means that the input may have something
wrong, such as input L and N line reversed or the grounding wire
is not connected properly.
2. If the load level is higher than 100%, the buzzer will beep one
every 0.5 second as a warning for the over-loading condition.
The user should remove unnecessary loads one by one, until the
load level become lower than 100%.
Line mode

EN
3. If the Battery LED flashes, it means that the battery is not
connected or the battery level is too low. In this case please
check the connection of battery and press test button for 2
seconds to test the battery. If the connection is normal, it’s
possible the battery is failed or aged. Please refer to the
common troubleshooting table in chapter 4.
Connecting AC Generator as Input
Remove the loads connected to UPS first. Activate the generator
and connect the output of generator with the input of UPS until the
generator operates stably, then turn on the UPS and add the loads
one by one.
Please choose the generator with output capacity which is twice
larger than the UPS capacity.
Battery mode
Battery mode means that the battery power goes through the DC/DC
section to the inverter (DC/AC) and output a stable backup power
when the mains are failed. If the mains recovered, the UPS will
transfer to line mode without interruption.
In battery mode, Battery LED and Inverter LED are turned on
constantly. If Line LED flashes at the same time, it means that the
input mains are abnormal.

EN
1. In battery mode, Buzzer beeps once every 4 seconds. Press test
button for 2 seconds in battery mode, UPS would be muted. To
resume the alarm, press test button again for 2 seconds.
2. When the voltage of battery decline to the lower limit, buzzer
beeps once every second to warn the low battery status and
remind user to turn off the loads.
3. User may check the backup function by turning on the UPS
without connecting the mains input.
Bypass mode
Bypass mode means that the UPS provides the power through the
internal bypass path 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 software tool.
In bypass mode, Line LED and Bypass LED are turned on constantly.
Buzzer beeps once every 2 minutes.
