EA900 series single in single out UPS

The second-generation EA900 series 1kVA-20kVAUPS is a new generation of universal UPS power supply designed and manufactured by Yishite Company based on the latest research and development achievements and application experience. It adopts advanced DSP digital control technology, effectively improving product performance and system reliability, and achieving higher power density integration and miniaturization

DSP digital control technology

By adopting advanced DSP digital control technology, the product performance and system reliability have been effectively improved, and higher power density integration and miniaturization have been achieved.

Active Input Power Factor Correction (PFC)

Adopting active power factor correction technology with digital control, the input power factor can reach 0.98 or above to avoid pollution to the power grid environment, achieve energy conservation, and reduce system investment costs.

Digital control of battery mode DC-DC converter

The 1-3KVA UPS adopts digital control, which changes the original battery mode DC-DC converter from analog control to digital control, improving reliability.

green and environmentally friendly

This series of products is a green and environmentally friendly product that complies with the requirements of the EU environmental directive RoHS and the national standards for pollution control and management of electronic information products. Under normal use, the products will not cause harm to human health or the environment.

Wide input voltage frequency range

The extremely wide input voltage and frequency range enable normal power supply even in remote areas with extremely harsh electrical environments, reducing battery discharge times and improving battery life.

Friendly human-machine interface

Rich UPS information display.

LCD display and LED status display.

Variable frequency function

Supports 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 by the panel to maximize battery utilization.

The output voltage is set to 208V/220V/230V/240V.

CF frequency conversion mode setting.

Output frequency setting in OPF frequency conversion mode.

Comprehensive protective measures

Integrated AC input overvoltage and undervoltage protection, output overload and short circuit protection, inverter overheating protection, IGBT overcurrent protection, battery undervoltage warning protection, and battery overcharge protection The integration of multiple functions such as protection greatly ensures the stability and reliability of system operation.

It has a bypass function, which can switch to the bypass working state without interruption when the output is overloaded or the UPS fails, and continue to supply power to the load from the mains, and provide alarm information.

Cold start and mains power start functions

In case of abnormal power supply, the UPS can be directly started with the battery to meet emergency needs.

The battery free state can directly use the mains power to start the UPS, which can be used as a high-precision stabilized power supply.

Can be used in conjunction with a generator

The input voltage and frequency range are wide, which can effectively isolate the poor power generated by the generator and provide a clean, safe, and stable power source for the load.

Zero switching

The dual transformation online design enables the output of the UPS to be a pure sine wave power supply with frequency tracking, phase-locked voltage regulation, noise filtering, and no interference from grid fluctuations, providing more comprehensive protection for the load. When the mains power is unstable, the transition time of UPS power supply mode is zero, effectively ensuring the safety and reliability of load operation.

Intelligent battery management

Adopting intelligent battery management technology and adopting an automatic float charging switching charging design.

Equipped with battery overvoltage, overcharge and other protection functions, it maximizes the protection of the battery from damage.

Powerful scalability features

The smart slot can provide rich expandable functions, including SNMP card, RS485, AS400 card, and EMD environment monitor.

50/60Hz power system adaptive

Automatic recognition, suitable for 50Hz/60Hz power systems, meeting the requirements of different power systems.
