2 Product Overview
2.1 Product description
This series on-line UPS is a high-performance and full-digital uninterruptible power supply using the
DSP control technology. The system uses online double-conversion topology design. The DC/AC
converter adopts SPWM technology, IGBT power module, and output isolation transformer.
Therefore, This series UPS is a kind of pure sine wave power supply with stable frequency stable
voltage (SFSV) output and without being affected by grid interference. This series UPS has wide
mains input voltage range, superior generator compatibility, strong load capacity, good load
compatibility, no switching time needed during the output, and other characteristics, which can
greatly meet the demands of various application environments.
Power range: 6-30KVA
Operating mode: intelligent power frequency online mode
Power supply mode: 1-phase in/1-phase out, and 3-phase in/1-phase out
Applications: finance, telecommunications, securities, tax administration, transportation,
insurances, governments, enterprises, etc.
2.2 Product features
Strong environmental adaptability
Strong grid adaptability: the input voltage of the 1-phase in/1-phase out UPS is within the
range of 165VAC to 275VAC; while that of the 3-phase in/1-phase out UPS is within the
range of 285VAC to 475VAC. The input frequency is within the range of 40Hz to 70Hz,
which can adapt to severe grid environment and various kinds of fuel generators.
Strong load capacity: this series UPS is compatible with mixed load along with strong
overload capacity.
Adjustable output voltage/frequency: according to the user needs, the output voltage and
the frequency can be respectively set at 220V/230V/240Vand 50/60Hz.
Double DSP control with high reliability
Independent bypass power supply: the bypass DSP automatically detects the state of the
main DSP. When there are abnormities on the main power panel or the main DSP, switch
the UPS to the bypass mode for output, and give an alarm at the same time, so as to
ensure the uninterruptible power supply for loads.
Strong charging capability
The charging current 2A, 4A, 6A, 8A, 10A and 12A can be easily set by DIP switch. This
series UPS (10Kand above) supports dual parallel charging panels. The maximum
charging current is 24A.
Support dual input, series hot standby, and parallel operation
It is easy to realize dual input, series hot standby, and parallel operation. Furthermore, it is
simple to operate, which can further improve the system reliability.
Input high voltage protection function
Monitor the input voltage of the rectifier. Disconnect the rectifier during the high voltage
input, so as to protect the safety of the inverter.
