Main features

1. Screen cabinet design, intuitionistic big screen LCD with Chinese, English display, LED status indication
2. The flow diagram running status visual display, intelligent icon touch button, tabular data display, events records display, Chinese and English optional menu operation
3. Inverter back-up work mode design, high speed static transfer switch
4. Intelligent digital control technology
Realize circuit control, parameters settings, running management, advanced self-check and self-detection function via adopting three pieces high speed MCU and CPLD, also self check all independent circuit connections of PCB boards and faults analysis. Via sine wave voltage of digital conversion, we can assure systems overstable running. Perfect new projects can meet our customers’ actual demand.

5. High-efficiency IGBT(Insulated Gate Bipolar Transistor) inverter technology
IGBT with excellent high speed switch feature, high voltage feature and large current feature. Drives by electric voltage, only need small control power.

6. Excellent load feature
It completely meet load step from 0-100% while no need change to bypass, and make sure the output stable, reliable

7. Perfect protection function
Input/output over/low voltage protection, input surge protection, phase sequence protection, battery over charge/discharge protection, short circuit protection, over-temperature protection and so on, as well as alarm function.

8. High-powered dynamic feature
Adopt kinds of feedback control such as instantaneous control mode and virtual value, not only realize the high dynamic adjustment, but also reduce the output voltage distortion.

9. Adopt 6 pulse rectifier charger, Intelligent battery management
Intelligent battery charge: automatically set the battery charge current parameter according to the battery capacity, and also reach the boost and float voltage transformation, temperature compensation and discharge management. Prolong the battery lifetime and reduce the administrator’s burden.

10. Selectable battery inspection module
Can measure single parameter and display on the LCD, Battery failure will immediately alarm and inform the administrator.

11. Intelligent detecting function
This system microprocessor can continually online detect power status, the breaker status and all the working status. Like meeting the faults, EPS immediately protect, alarm and notice the administrator.

12. Intelligent communication interface
With RS232 and RS485 standard collocation, optional SNMP, selectable dry connector, adopt non-source contactor to reach the monitor of the EPS.
