to determine whether the voltage and frequency are normal. If normal,
UPS will turn on automatically to supply power to loads; if abnormal,
UPS will start charger to charge the battery. The UPS will not turn
on to supply power to loads until the voltage and frequency of the
main power restore normally.
11.Cold start function. When there is no main power, UPS can be started
by battery pack. It can meet the users' emergency needs. The cold
start function is quite strong. UPS can be cold started under the full
load situation.
12.UPS protection function:
When the main power input/output voltage is too high or too low,
overload, short-circuit, inverter temperature is too high, low
voltage
and overcharge of battery, network surge and so on, UPS has a
protection function.
13.Rack-Tower conversion LCD design. No matter what angel to watch
the display, only press the key slightly can meet your perspective
needs. The content displayed on the interface is rich. The capacity
of the loads and the battery can be saw directly and the FLASH pictures
and fan rotating icon can be displayed when charging. So it is easy
to know it's operation. When UPS fails, it can show the fault code,
the machine can be maintained as soon as possible by inquiring fault
code table.
14.The UPS can communicate with the computer with intelligent UPS
monitoring software through the RS232 interface. All the parameters
clearly display on the communication interface. Computer can control
multiple functions of the UPS directly.
15.Via internal or external SNMP adapter, UPS can go on internet and
provide the latest information and power messages. You can monitor
and manage the UPS status through all kinds of network management
system.
16.Convenient USB communication. You can see the operation of the
machine completely. Even if the RS232 interface is occupied or
connected at the same time, it will automatically switch to USB
connection.
17.ECO function can help you save electricity. When the input mains
power is in a fixed range, the loads is supplied with power by mains
power directly, the inverter is on waiting; when input mains power
is abnormal, it transfers to inverter to supply power to loads at once.
18.In order to ensure the power of the important loads can last for
a long time, you can plug the important loads into the second power
down socket. When the battery voltage is below the predetermined value,
only the first cut-off power socket is broken off, the second power
down can keep on supplying power until the battery voltage reaches
protect point and shut down.
19.Adopt international standard rack-mounted size. Whether you want
to put it on the office desk or in the rack-mount as a system to manage,
It can present your personal style with corresponding components.
