EA300 series backup UPS

The EA300 series 500VA-1500VA product is a new generation of intelligent UPS launched by our company using advanced microcomputer (CPU) control technology. It has many functions such as input voltage regulation, short circuit protection, automatic frequency adjustment, output overload protection, battery charging management, etc

high reliability

Advanced microcomputer (CPU) control technology enables faster and more accurate data processing and control.

Interactive design, during normal system operation, the system uses AC to DC to charge the battery and replenish its charge, ensuring that the built-in battery has sufficient energy.

We use advanced Hall devices, international quality components, and high standard production management to provide users with a reliable power protection foundation.

LED and LCD display modes

The EA200's intuitive LED status display combined with buzzer indication allows you to have a clear understanding of the UPS operating status; The large screen LCD display of EA300 can provide you with real-time parameters such as UPS input and output voltage, frequency, battery capacity, load situation, etc.

Ultra wide input range

UPS has automatic online voltage regulation and safe operation from 162~295VAC input; Effectively reducing battery usage and extending battery life, especially suitable for areas with large power grid fluctuations and poor power environments.

High speed synchronous conversion

The system has the function of automatically tracking the phase of the mains power, ensuring that the output voltage of the inverter is completely in phase with the mains voltage, effectively reducing the conversion time of the UPS and the peak surge voltage generated during switching, ensuring minimal interference to electrical equipment.

Unmanned security shutdown

When there is a long-term power outage, this system can cooperate with UPSmart2000R/UPSmart2000I software through RS232 serial port or USB port to provide alarm prompts and automatic safe shutdown actions for the connected system.

Intelligent Error Prevention Technology (LCD)

Using microcomputer control, long press for 3 seconds (power on/off) can effectively control unnecessary power loss caused by human error.

Smart Charging

Battery temperature compensation technology ensures a longer lifespan for battery applications.

Three charging technologies with shorter charging time.

Multi protection system

The machine is equipped with advanced Hall devices, which can prevent UPS overload damage caused by connection errors. The UPS will automatically shut down the system output.

The machine is equipped with a precisely controlled power protection circuit, which eliminates interference such as surges, lightning, low voltage, and peak voltage. Fast fuses provide short circuit and overload protection.

International level anti conduction standards will not cause any interference to your power supply.

International level radiation protection standards can ensure your health and peace of mind.

Intelligent no-load automatic on/off technology (LCD)

When the mains power is supplied, the UPS will automatically turn on without any operation and will also charge the battery.

When the equipment is in a shutdown state and there is a power outage, the system will automatically detect the load. If the load is less than 5%, the UPS will be judged as an unloaded state and automatically shut down after 1 minute, reducing losses and effectively extending the service life of the battery.

Automatic frequency selection technology

After UPS is connected to the mains power, the system will automatically adjust the inverter frequency according to the input frequency, relieving users of the worry of 50/60HZ power supply.

Home PCs, SOHO small office environments, small communication switches, SOHO network equipment, commercial POS machines, workstations and their peripheral devices, etc
