The second generation EA900 series 1-3kVA  UPS is a new generation of universal UPS power supply designed and manufactured by Yishite with the latest R&D achievements and application experience. It adopts advanced DSP digital control technology to effectively improve Product performance and system reliability, and achieve higher power density integration and miniaturization. At the same time, in order to meet the personalized needs of users in all aspects, high-end low-power online UPS power products specially launched for the needs of domestic and foreign small and medium enterprises and small power supply environments can be used for user departments and servers, small local area networks, workstations, and industrial control Machines, small medical equipment, and various small precision electronic instruments provide high-reliability power protection.

​

Adopt advanced DSP digital control technology, effectively improve product performance and system reliability, and achieve higher power density integration and miniaturization.

Active input power factor correction (PFC)

Adopting digitally controlled active power factor correction technology, so that the input power factor is as high as 0.99 or more, so as to avoid pollution to the grid environment, achieve energy saving, and reduce system investment costs.

Digital control of battery mode DC-DC converter

Using digital control, the original battery-mode DC-DC converter is changed from analog control to digital control to improve reliability.

This series of products are green and environmentally friendly products that meet the requirements of the European Union's environmental protection directive RoHS and the requirements of the national electronic information product pollution control and management standards. Under normal use of the product, it will not cause harm to humans and the environment.

Extremely wide input voltage and frequency range, it can supply power normally even in remote areas with very harsh power environment, reducing battery discharge times and improving battery life.

Rich UPS information display;

LCD display and LED status display;

Support 50Hz/60Hz output or 60Hz/50Hz output frequency conversion mode to meet the special requirements of users;

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

The low battery protection point (EOD) can be flexibly set to maximize battery utilization; the output voltage is set to 208V/220V/230V/240V; there are also multiple functions that can be set through the panel or background, such as ECO economic operation Mode, EPO emergency shutdown, etc., it is convenient to support a variety of personalized customization needs.

Integrated AC input over-voltage and under-voltage protection, output overload, short-circuit protection, inverter over-heat protection, IGBT over-current protection, battery under-voltage warning protection and battery over-charge protection and other multi-function protections in one, which greatly guarantees Stability and reliability of system operation;

With bypass function, when the output is overloaded or the UPS fails, it can go to the bypass working state without interruption, and the mains will continue to supply power to the load, and provide alarm information;

It has an alarm display function. When there is any abnormal situation, the UPS will sound and light alarm and display the current alarm information in real time, which is convenient for users to find and eliminate the abnormality;

Using the battery to start the UPS directly in the abnormal situation of the mains power supply to meet the emergency needs;

When there is no mains power, the UPS can be started directly with mains power, which can be used as a high-precision stabilized power supply;

Wide input voltage and frequency range, can effectively isolate the bad power generated by the generator, and provide a clean, safe and stable power supply for the load

Double-conversion on-line design makes the output of UPS a pure sine wave power supply with frequency tracking, phase-locking voltage stabilization, filtering out noise, and not being interfered by power grid fluctuations, providing more comprehensive protection for the load. When the mains is unstable, the conversion time of UPS power supply mode is zero, which effectively guarantees the safety and reliability of load operation;

Adopt intelligent battery management technology, and use the charging design with automatic equalization and floating charge switching;

It is equipped with battery overvoltage, overcharge and other protection functions to protect the battery from damage to the maximum extent;

The smart slot can provide a wealth of expandability functions, and you can choose SNMP card, RS485, AS400 card
