Product Description
EA890 Online UPS 3/3
Features
Intelligent Digital Control
1. With high speed MCU control system, the online UPS can achieve parameter setting, running progress management, self-test, self-detective, and so on. It can also detect all the independent circuits, and do faults protection.
2. Advanced DDC (Direct Digital Control) technology, DSP (Digital Signal Processor) technology and special IC are used. This keeps UPS with perfect performance.
3. Advanced IGBT (Insulated Gate Bipolar Transistor) with high speed switch, high voltage and large current makes efficiency higher, driver circuit smaller, and improves the system efficiency and reliability.
100% Unbalance Load Capability
Due to 3-phase independent modulation and full bridge inverter design, the online UPS supports 100% unbalanced load.
Intelligent Battery Management
This online UPS comes with rectifier and charger integrated design. The charging capacity is configured according to battery capacity. User can set up parameters via the operation platform, and the charging current can be configured by software automatically. Users can also configure battery self-test, charging and discharging interval time, thus extending the service time of batteries.
Optional Communication Interface
RS232/RS485 and several dry contacts can be used for communications and remote control.
Functional LCD display
The online UPS is designed with a large LCD display which can show UPS running status, running progress, UPS parameter data, and fault events, etc.
Perfect protection
The online UPS comes with various system protection functions, such as over voltage, low voltage, over current, over load, and short circuit protection functions.
Parallel (Option)
1+1 parallel
