The second generationEA900series1KVA~20KVA UPS EAST is a new generation of general design and manufacture of the latest R & D achievements and application experienceUPSThe power supply adopts advancedDSPDigital control technology effectively improves the product performance and system reliability, and realizes the integration and miniaturization of higher power density. At the same time in order to fully meet the individual needs of users, online and for high-end small power type domestic and foreign small and medium-sized enterprises and small power supply environment needs specially launchedUPSPower supply products for users of the departmental servers, LAN, workstation, computer, small medical equipment, and other small precision electronic instruments to provide high reliable power protection.

Application domain:

  The small and medium-sized enterprise data center, the financial system of small outlets, industrial automation control system, network server, communication base station server, Internet cafes, shopping malls cashier etc..

Performance characteristics:

1.DSPDigital control technology

  1Adoption of advancedDSPDigital control technology effectively improves the performance and reliability of the system

  Integration and miniaturization of higher power density.

2.Active input power factor correctionPFC

 1The active power factor correction technique with digital control makes the input power factor as high as possible0.98Above, in order to avoid the pollution of the grid environment, to achieve energy saving, reduce the cost of the system investment purposes.

3.Battery modeDC-DCDigital control of converter

 11~3KVA UPSUsing digital control, the original battery modeDC-DCThe converter is changed from analog control to digital control, and the reliability is improved.

4.Green environmental protection

 1This series of products is green environmental protection products, in line with the EU environmental directivesRoHSThe requirements of the national electronic information products pollution control management measures standards, products in normal use, will not cause harm to the human body and the environment

5.Wide input voltage frequency range

 1) the input voltage and frequency range very wide, can the normal power supply power even in the remote areas of the environment is very bad, reduces the battery discharge times, improved battery life.

6.Friendly man-machine interface

 1RichUPSInformation display.

 2LCDDisplay andLEDStatus display.

7.Frequency conversion function

 1Support50Hzinput/60HzOutput as well60Hzinput/50HzOutput frequency conversion mode, to meet the user's

Special needs

8.Panel setting function

 1ECOSet up。

 2BatteryEODThe point can be flexibly set up by the panel, and the utilization ratio of the battery is maximized.

 3Output voltage setting208V/220V/230V/240V

 4CF Frequency conversion mode setting.

 5OPF Output frequency setting under variable frequency mode.

9.Perfect protective measures

 1AC input overvoltage protection, output overload, short circuit protection, inverter overheating protection,IGBTOvercurrent protection, undervoltage protection and warning the battery battery overcharge protection and other functions of protection in one, greatly ensure the stability and reliability of the system.

 2With bypass function, when output overload orUPSWhen the fault occurs, the power supply can be continuously switched to the bypass operation state, and the power supply is continuously supplied to the load, and the alarm information is provided.

 3Input zero line detection function. AvoidableUPSThe power supply is connected to the zero fire line

10.Cold start and city power start function

 1The abnormal condition of city electricity can be started directly with batteryUPSMeet the emergency needs.

 2No battery status can be directly initiated by mains powerUPSIt can be used as high precision stabilized voltage power supply.

11.It can be used with generators

 1The input voltage and frequency range is wide, which can effectively isolate the bad power generated by the generator, and provide clean, safe and stable power for the load.

12.Zero handover

 1Double conversion online design enablesUPSThe output is a pure sine wave power supply with frequency tracking, phase locking, noise filtering and disturbance free from grid fluctuation, providing more comprehensive protection for the load. When the city electricity is unstable,UPSThe switching time of the power supply mode is zero, which ensures the safety and reliability of the load operation effectively.

13.Intelligent battery management

 1) using intelligent battery management technology, using three stepcharging, effectively prolonging the service life of the battery, reducing the number of battery maintenance; the regular self-examination of the battery, the timely discovery of the battery problem.

 2With battery overvoltage, overcharge and other protection functions, the maximum protection battery is not damaged.

14.Powerful extensibility

 1Smart slot provides a rich range of scalable features, selectableUPSmart 2000Monitoring software,SNMPCard,RS485AS400Card,EMDEnvironmental monitor

15.50/60Hz Adaptive power supply system

 1Automatic identification and adaptation50Hz/60HzThe power supply system meets the requirements of different power systems.
