High reliability design
◆Double conversion online topology design enables UPS output
frequency tracking, phase locking, voltage stabilization and noise
filtering, and is not affected by power grid fluctuations. Pure
sine wave power supply, UPS output provides more comprehensive and
perfect protection for user equipment.
◆Advanced modular dual CPU control has reliable overall operation
and high stability, ensuring the overall efficiency of UPS safe
operation.
◆CPU controls the charging of current, and the charger periodically
charges the current according to the capacity of the battery. ◆The
input harmonic filter meets American and European standards,
allowing UPS to reduce the pollution of mains feedback and not
affect other devices sharing the same mains input.
◆Adopting advanced power factor correction PFC technology, the
input power factor is almost 1 regardless of how the load and mains
voltage change.
◆ Wide AC input voltage range: 380VAC±25%, avoid frequent switching
to battery power, and adapt to areas with harsh power environment.
◆Using high-frequency filtering synchronization circuit, fast
tracking of synchronization frequency and power gradual growth
function, reduce the requirements for generators, and the capacity
is only twice the UPS input power.
◆Harmonic filters are set at the input and output to minimize the
harmonic interference of UPS to the power grid.
◆DC start function can directly start the UPS when there is no
mains power to meet the user's emergency needs.
Perfect whole machine protection capability
◆It has multi-function protection such as
output overload protection, output short circuit protection,
inverter over-temperature protection, battery undervoltage warning
protection and battery overcharge protection, which greatly ensures
the stability and reliability of system operation.
◆Equipped with manual maintenance switch, when UPS fails, it can
switch to bypass working state without interruption and continue to
supply power to the load from the mains, making maintenance work
easy, convenient and fast.
Interface management function
◆ LCD display can record UPS working status, parameter information,
etc. in real time, making it convenient for users to manage UPS .
Network monitoring management
◆Through RS232/RS485 communication interface, SNMP network adapter,
and UPS intelligent monitoring software, it can communicate with
the computer. Various UPS parameters are clearly displayed on the
communication interface.
Optional intelligent battery monitoring module
◆ Can detect single cells, with overvoltage, undervoltage and
differential pressure alarm functions, if there is a battery
failure, it will be displayed on the screen and the administrator
will be notified.
High environmental adaptability
◆ The circuit board is placed in a completely enclosed space and
treated with "three-proof" coating, which is more suitable for the
harsh environment of tunnels and squares.
