module's biggest single module to 40kw.
■ UPS power module supporting hot swappable, capacity upgrade
extremely simple.
■ Super ability for overload and short circuit, ensure the system
stability and safety under the limit state of system.
■ Core control adopts advanced DSP and digital technology, the
system stability is higher.
Application:
IDC(Internet Data Center),computing center,ISP(Internet Service
Provider ),Telecom,
Finance bank and securities,Tax,hospital system, industrial
automation, precision equipment, etc.
CNM330 series is modular online UPS for sensitive equipments. The
single cabinet power rating covers from 15KVA to 300KVA which
delivers the best of combination of reliaability, hot-swappable and
flexibility. With the latest IGBT three-level technology and DSP
control, CNM330 achieves a high input power factor, low THDi
Modular design with N+X redundancy and online hot swapping easy to
expand the capacity Full DSP control of high stability, reliability
and safety Integrated IGBT module with improved performance and
reduced size.
Working principle:
Modular UPS use double conversion on-line structure,including the
rectifier, inverter, battery charger, control circuit, the input
and output battery connector breaker. Have function that is input
power factor compensation. All modules can be online hot-swappable,
provide the highest level of availability, and maintainability.
If one power module failure will not affect the system normal
working, power module can be online hot-swappable all power module
parallel is managed by the control board, in accordance with the
unified parameters running, one power module fault can be
automatically exit parallel system, will not cause harm to the
whole parallel system.
Modular UPS system use independent static bypass module,do not use
multiple static bypass structure,avoid caused overload damage
Modules because of multiple bypass module uneven current when UPS
turn to bypass working.Themodule paralleloutput voltage accuracy
is±1%,parallel circulation current<1%.
Static bypass module contains bypass static switch only, excluded
static switch of the main circuit output; therefore, replacing
static bypass module will not cause the system power down or
transfer manual maintenance bypass,which can realize online
hot-swap replacement.
