★ Technical features of EA890 series 10-120kVA UPS

● Intelligent digital control

Using a high-speed microcontroller to realize real-time control, parameter setting, running program management, self-checking and self-checking, etc., it can detect and fail protection for all independent circuit connections on the circuit board.

Advanced DDC (Direct Digital Control) technology, DSP (Digital Signal Processor/Digital Signal Processor) technology and the use of special ICs make the product have excellent performance.

The advanced IGBT module (Insulated Gate Bipolar Transistor) has good high-speed switching, high voltage, high current and other working characteristics, high working efficiency, miniaturized drive circuit, and effectively improves the overall efficiency and reliability of the product.

● Allows 100% unbalanced work

Using three-phase independent modulation and full-bridge inverter technology, it can supply power normally and reliably even when the three-phase load is 100% unbalanced.

● Intelligent battery management function

Using the integrated design of rectifier/charger, parameter settings can be made through the operation interface according to the battery configuration capacity, and the charging current can be automatically adjusted by the software. At the same time, the automatic battery detection and charging/discharging interval time can be set according to the safety of the grid , Extend battery life.

● Rich communication function interface

Built-in RS232/RS485 communication port and multiple dry contact signal interfaces, truly realize multi-purpose communication and remote monitoring.

● Powerful Chinese/English display interface

Using a large-screen LCD touch screen as the main display interface, the display content can be selected and set in Chinese/English, and the running status, operating procedures, data collection, fault detection materials and other content are clear at a glance.

● Complete protection functions

It is equipped with multiple system protection functions to detect and alarm abnormal conditions such as overvoltage, undervoltage, overcurrent, overload, and short circuit. It also has reliable protection functions and has strong environmental adaptability.
