Precision Equipment Modular UPS System High Stability Three Phase
30 - 300KVA
Description:
CNM330 series is modular online UPS for sensitive equipment. The
single cabinet power rating covers from 10KVA to 300KVA which
delivers the best of combination of reliability, 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
Application:
Application IDC(Internet Data Center)
Computing center
ISP (Internet Service Provider )
Telecom , Finance, bank and securities , Tax
Hospital system , industrial automation
Precision equipment, etc.
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. The module parallel output 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.
Rich Management Interface
Advanced battery management
- All floating automatic conversion
- Temperature compensation
- Discharge to suspend automatic voltage regulation
- Battery self-diagnosis and self-inspection
- Battery capacity prediction
- Discharge time estimates
- Low voltage forecasting warning
Data recorder:
Every 10 ms records a core electrical data, and in Fault occurs,
the freezing failure 1 to 1.5 before work. The core of the cycle
frequency electrical data Accurately record the cause of failure,
to help the accident diagnosis and accurate positioning Rapid
diagnosis to improve maintainability, the data will be recorded
before a failure or overload occur.
Advanced self-diagnosis:
- Inverter and rectifier circuit working condition monitoring
- Battery capacity and status detection
- Equipment working environment temperature testing
- Ease of maintenance and management of equipment
- Can each fan of fault detection, and replace the fan without power
