The next generation of EA900 series 1kVA-20kVAUPS is yishite company set 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 use of advanced DSP digital control technology, improve the product performance and system reliability, and achieve higher power density integration and miniaturization.
The input active 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 battery mode DC-DC converter
1~3KVAUPS adopts digital control, the original battery mode DC-DC converter from analog control to digital control, improve the reliability of the.
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 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.
The friendly man-machine interface
The rich UPS information display.
LCD display and LED display.
The frequency conversion function
Support 50Hz input /60Hz output or 60Hz input /50Hz output frequency mode, to meet the special needs of users.
The panel setting function
Battery point EOD can be flexibly set by the panel, the battery utilization maximization.
The output voltage setting 208V/220V/230V/240V.
Set the CF variable frequency mode.
OPF frequency conversion mode output frequency setting.
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 electric start function
An abnormal condition can be directly used batteries to start UPS, to meet the emergency needs.
No battery state can directly use electricity to start UPS, can be used as high precision DC power supply.
Can the use of collocation generator
Wide range of input voltage and frequency, can be effectively isolated adverse power generator, power supply, clean safe and stable load.
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. An unstable, UPS power supply mode switching time is zero, effectively guarantee the safety and reliability of load operation.
Intelligent battery management
The intelligent battery management technology, the use of automatic charging design float switch.
A battery voltage, overcharge protection function, to maximize the protection of the battery is not damaged.
Intelligent slot can provide abundant expansibility function, can choose SNMP, RS485 card, AS400 card, EMD environment monitor.
Adaptive 50/60Hz power system
Automatic recognition, adaptation of 50Hz/60Hz power system, to meet the requirements of different power supply system.
