| - SI900 Series |
Ideal applications : |
| - SI8600 Series |
Centralized server center, network control center, Information center |
| - SI8900 Series |
Features : |
| UPS for Banking Solution |
100% digital technology |
| Switching Power Supply |
Self-diagnosis, circuit control, parameters setting and program management are based on 3 high speed micro-
controllers. |
| DC Power Supply |
Applies high-tech components |
| AC Power Source |
DDC (Direct Digital Control), DSP (Digital Signal Processing), ASIC (Application Specific IC) and CPU are used
in this system. |
| Variable Transformer |
Super performance from IGBT |
| Energy Saving |
High speed on/off, operating on high voltage and large current, simple gate control circuits (voltage-
controlled), high efficiency and high stability. |
| Other |
Fully meets sharp load fluctuation from 0 to 100% |
| |
Completely meet the requirements of sharp load flutuation without transferring to bypass, and maintain the
output within tolerance. |
| |
Large sreen LCD display |
| |
Users can conveniently operate the UPS according to the instructions and easily get UPS operating status at
any time via large screen LCD. |
| |
Perfect protections |
| |
Built-in over/low-voltage, over-current, overload amd short circuit protections ensure lowest failure rate. |
| |
Low output voltage distortion |
| |
Owing to partial circulating current control, inverter could rapidly control impulse current from load change
|
| |
and surge. UPS can quickly respond to load change via feedback control. |
| |
Intelligent battery management |
| |
UPS will automatically charge and discharge the battery in float charging or boost charging mode according to |
| |
the cycle set by the internal software and automatically maintain the battery without manual operation,
which prolongs the battery life. |
