Products Information

EA990 high frequency online ups possess of double DSP control technology with high capability and complete digital control. Its performance is better the same rating product from other manufacturers at home and abroad in current market. Further more its price is absolutely competitive compared with international manufactureres.

Idea Application
ISP (Internet Service Provider ), IDC（Internet Data Center）, network control center/computer centre, the charge system, Bank/Bond settlement centre, business server, Industrial process control application, Office automation system and precision instruments ect.

Features & Benefits
1. Three phase in three phase out; support 380/400/415V, 50/60Hz power grid systems
2. True online dual converstion; provide with high quality power(±0.5%)
3. Double DSP with complete digital control; make IGBT rectifier, inveter, charge, discharge and convertor be completely high frequency digital
4. UPS can carry 100% non-balance load, and half wave load;
5. Wide input voltage anti-jamming range(-40%～+20%) and frequency range(40～70Hz),adapt to bad power gird environment
6. Green power technology; High input power factor(0.99), low harmonic current(THDI<3%); energy-saving
7. Perfect output short circuit protection
8. 1+1 redundant assistant power supply design
9. N+N redundant design for the cooling fan of the main power components
10. Online sense and protection function for components state: all of IGBT, SCR, fuse, fans ect states can be inspected on line and alarm by buzzer and LCD display
11. Intelligent battery management, prolong the battery life
12. Large LCD screen display, friendly Human-Machine Interface, thousands pieces of history record memorized
13. Blow front face in, blow upward out; This online ups is convenient to install other matched cabinet side by side, and the back door can be installed against wall to save space;
14. Similar Modularize Design, easy maintenance
15. Complete Maintenance can be done from front, all components maintenance and replacement can be done from the front door, and don't need to move unit or take down the side door.
16. Adopt air intake screened, and separate duct from inductance and module, Make sure no dust accumulated inner UPS, improving unit reliablity and prolonging the fan life.
17. Support up and down wire conection manner
18. Dispersive parallel technology; support redundant parallel（up to 6）and expansion online (Next version)
19. Digital circumfluence technology, small circumfluence and high reliable parallel (Next version) are the main features of our online ups.
20. Options---Main circuit backfeed protection, bypass backfeed protection, battery leakage protection, battery cold start function (Next version)
