EA990 Online UPS 3/3

EA990 high frequency UPS possesses double DSP control technology with high capability and complete digital control. In the current market, its performance is better the same rated product from other manufacturers at home and abroad. Its price is absolutely competitive when compared with international manufacturers.

Features
1. Three phase in three phase out is designed to support 380/400/415V, 50/60Hz power grid systems.
2. Our product features true online dual conversion function to provide high quality power ±0.5%.
3. Double DSP with complete digital control makes IGBT rectifier, inverter, charge, discharge and convertor completely high frequency digital.
4. UPS can carry 100% non-balance load and half wave load.
5. It has a wide input voltage anti-jamming range from -40% to 20% and a frequency range from 40 to 70Hz. It is able to adapt to a bad power gird environment.
6. This online UPS has features of high input power factor up to 0.99, green power technology, low harmonic current THDI<3%, and saves energy.
7. The EA990 series of online UPS is equipped with perfect output short circuit protection and 1 1 redundant assistant power supply design.
8. N N redundant design for the cooling fan of the main power components.
9. Online sense and protection function for components state, like IGBT, SCR, fuse, fans, etc. All of them can be inspected online and alarm by buzzer and LCD display.
10. Intelligent battery management is used to prolong the battery life.
11. It features a large LCD screen display, friendly human-machine interface, and thousands of pieces of history record memorized.
12. Blow front face in, blow upward out. It is convenient to install a matched cabinet side by side and the back door can be installed against the wall to save space.
13. Similar modularize design makes it easy to maintenance.
14. Complete maintenance can be done from the front, all components maintenance and replacement can be done from the front door, so there is no need to move the unit or take down the side door.
15. Adoption of air intake screened and separate duct from inductance and module, make sure no dust is accumulated inside UPS. This improves unit reliability and prolongs the life of the fan.
16. It supports up and down wire connection.
17. The online UPS 3/3 uses dispersive parallel technology to support redundant parallel up to 6 and expansion online.
18. The digital circumfluence technology has functions of small circumfluence and high reliable parallel.
19. It has optional main circuit back feed protection, bypass back feed protection, battery leakage protection, and battery cold start function.

Applications
Our EA990 online UPS 3/3 is applicable to internet service providers (ISP), internet data centers (IDC), network control centers or computer centers, the charge system, bank and bond settlement centers, business servers, industrial process control applications, office automation systems, precision instruments etc.
