The second generation of EA900 series 1kVA-20kVAUPS is the EAST company in the latest research results and application experience, a new generation of universal design and manufacture of the UPS power supply, adopting advanced DSP digital control technology, improve the product performance and system reliability, and achieve higher power density integration and miniaturization. At the same time in order to fully meet the individual needs of users, online high-end small power UPS power supply products for domestic small and medium-sized enterprises and small power supply environment specifically introduced, as users of the departmental servers, LAN, workstation, computer, small medical equipment, and other small precision electronic instruments provide high reliability power protection.

DSP digital control technology

  The advanced DSP digital control technology can effectively improve the performance and reliability of the system, and realize the integration and miniaturization of higher power density.

 

Active input power factor correction (PFC)

  Active power factor correction using digital control technology, the high input power factor is more than 0.98, to avoid environmental pollution on the power grid, to achieve energy saving, reduce the investment cost of the objective system.

 

Digital control of battery mode DC-DC converter

 1~3KVAUPS uses digital control to transform the original battery mode DC-DC converter from analog control to digital control, thus improving the reliability.

 

Green environmental protection

 This series of products for green products, meet the requirements of EU directive RoHS and 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.

 

Wide input voltage frequency range

 Input voltage and frequency range is extremely 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.

 

Friendly man-machine interface

  Rich display of UPS information.

  LCD display and LED status display.

 

Frequency conversion function

  Support 50Hz input /60Hz output or 60Hz input /50Hz output frequency conversion mode, to meet the special needs of users.

 

Panel setting function

  ECO setting.

  The EOD point of the battery can be flexibly set up by the panel, and the utilization ratio of the battery can be maximized.

  Output voltage setting 208V/220V/230V/240V.

  CF frequency conversion mode setting.

  Output frequency setting in OPF frequency conversion mode.

 

Perfect protective measures

 Set the AC input overvoltage and undervoltage protection protection, output overload, short circuit, IGBT inverter overheat protection, overcurrent 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.

 With bypass function, when the output overload or UPS failure occurs without interruption to bypass state by electricity to supply power to the load, and provide alarm information.

 

Cold start and city power start function

  The abnormal condition of city electricity can start UPS directly with battery to meet the emergency demand.

  Without battery status, UPS can be directly used to start the power supply, which can be used as a high-precision regulated power supply.

 

It can be used with generators

  The 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.

 

Zero handover

  Double conversion on-line design, so that the output of the UPS tracking, phase-locked regulator, noise filtering, interference from the power fluctuations of pure sine wave power supply frequency, to provide more comprehensive protection for the load. When the power supply is unstable, the switching time of the UPS power supply mode is zero, which ensures the safety and reliability of the load operation.

 

Intelligent battery management

 The intelligent battery management technology, the use of automatic charging design float switch.

  Battery overvoltage, overcharge and other protection functions, the maximum protection of the battery is not damaged.

 

Powerful extensibility

  Smart slot can provide a wide range of scalable functions, you can choose SNMP card, RS485, AS400 card, EMD environment monitor.

 

Adaptive 50/60Hz power supply system

 

  Automatic identification, adapt to the 50Hz/60Hz power system, meet the requirements of different power systems.
