KW8000 SERIES UPS
KW8000 SERIES UPS is made for IDC, Enterprise data centers, Industrial process equipment, Laboratories, etc. It provides reliable power protection and advanced technology for high power applications. It offers excellent dynamic performance, with the ability to handle virtually any input condition while still providing computer grade output to critical loads.
CHARACTERISTICS
True double convertion on-line UPS with capacity from 100kVA to 600kVA
High level quality battery packs to guarantee back-up time
Isolation transformer, which suits for precision load and increase reliability
Great capacity to power 100% unbalanced load
Up to 4.8 MW UPS capacity when working in parallel
Patented power electronics and magnetics ensures 0s transfer time to inverter
Double DSP-Chips Control to increase flexibility, safety, reliability, and stability.
Technology Features
Input Performance
Robust Rectifier for Wide Input Range
The wide AC input voltage and frequency window avoids unnecessary battery discharge even when operating from an unstable AC source (i.e. Diesel Generator). SCR Rectifier is ok to increase Input PF, and extra harmonic filter for input is available to make the Input PF to 9.4.
Programmable Soft Start
Allows the rectifier to ramp up in a programmable time period (6-100s settable) eliminating in-rush current. This feature reduces the need of oversizing the input power system (gensets, feeder cables, and overcurrent devices).
Generator Compatibility
User-programmable features such as slew rate, phase angle rate-of-change and voltage rate-of-change allow the UPS to quickly sync to a genset during emergency back-up. GE's optional input filter also has user-programmable features ensuring quick and continuous synchronization to generator voltage.
Easier Installation and Configuration Flexibility
· Top or bottom cable access
· Matching battery and maintenance bypass cabinet for easy configuration
· Front Maintainability Design reduces mean time to repair
Scalable Solution
· Scalable Solution
· Redundant Parallel Architecture (RPA) provides reliability, redundancy and scalability
· Parallel up to 8 UPS Modules
· Long history of experience with Redundant Parallel Architecture (RPA) which increases system reliability by eliminating single point of failure
Output Performance
Total Harmonic Distortion (THD)
A distorted output voltage waveform affects the proper function of the load's equipment. The KW8000 Series has very low output voltage THD, even with connected 100% unbalanced or 100% non-linear loads.
Transient Response
With the use of SVM and the ZigZag transformer, the KW8000 UPS can react very quickly to zero-100% step loads (within 1/3 cycle). This reduces the need to oversize the UPS for severe pulse-load applications.
Overload Capabilities
The KW8000 Series UPS has a robust inverter capable of delivering 150% overload for 60 seconds, 110% for 1hour and 105% for long time working.
Phase Load Imbalance
The UPS Output ZigZag transformer, via its inherent characteristics and windings configuration, provides excellent voltage regulation against phase-to-neutral (Ph-N) load imbalances.
Parallel architecture
Redundant Parallel Architecture(RPA) System
Configuration
Kewang provides RPA, a unique technology that can parallel UPS modules with true redundancy by eliminating any single point of failure. RPA provides a scalable paralleling technique that reduces operating footprint and increases system reliability by eliminating the need for external paralleling equipment and cabinets (centralized bypass and master control).
One of the UPS modules in the system intelligently takes the leadership role, while the other UPS modules have access to all control parameters. If one UPS fails to operate, the load is automatically redistributed among the others. If the lead UPS fails to operate, then another UPS automatically takes on the leadership role. Kewang's RPA technology is implemented by distributing the control electronics within each UPS module in the system.
RPA System Advantage
No single points of failure Online Maintenance
Scalable and Modular Sequential Soft Start
Redundant Communication Smaller Footprint
Distributed Control Logic
