EA200/300 series of 500VA-1500VA products is our company adopts advanced microcomputer (CPU) a new generation of intelligent control technology to launch the UPS, with input voltage regulator, short circuit protection, automatic frequency regulation, output overload protection, battery charge management and other functions. Show the humanized using LED and LCD methods, the present state of LED can not only through the intuitive understanding of the equipment, part of the UPS is provided by LCD input / output voltage, frequency, load, battery capacity and other operating parameters. UPS also connects with the computer network through the RS232 serial port, the user can monitor the operation of UPS according to the software in real time. The series of UPS with high reliability, high precision, high stability and elegant appearance, to meet the requirements of the use of more users, the ideal protection power supply is computer and peripheral electronic equipment.
Advanced micro computer (CPU) control technology, more rapid and accurate data processing and control.
Interactive design, in the normal operation of the system, the system uses AC to DC battery charging, battery charging, to ensure that the built-in battery has enough energy.
Using advanced Holzer devices and international quality components as well as high standard production management to provide the assured power protection foundation for users.
LED and LCD display mode
EA200 direct LED status display with buzzer instructions, so you are well aware of the operation state of UPS; EA300 large screen LCD display can provide you real-time UPS input, output voltage, frequency, battery capacity, load and other parameters.
Ultra wide input range
UPS has an automatic voltage input from the 162~295VAC online, the operation safety; reduce the battery usage, thereby prolonging the service life of the battery, especially for large power grid fluctuations, the areas of poor environment.
High speed synchronous conversion
The system has automatic tracking power phase function, ensure that the inverter output voltage and the voltage of complete phase, effectively reduce the conversion time of the UPS and the peak surge voltage generated when switching, ensure the interference on the electrical equipment to the minimum.
Unattended safety shutdown
Hair growth time off, the system can through the RS232 serial port or USB port is connected with UPSmart2000R/UPSmart2000I software, system alarm and automatic shutdown safety action.
Intelligent error proofing technology (LCD)
Microcomputer control, long press 3 seconds (switch machine), can effectively control human misoperation, resulting in unnecessary power loss.
Battery temperature compensation technology, battery life longer.
The three charging technology has shorter charging time.
Multiple protection system
There are advanced Holzer devices in the machine, which can prevent the connection error from causing UPS overload damage. UPS will automatically and shut down the system output.
The power supply protection circuit with precise control is built in the machine to eliminate the interference of surge, lightning, low voltage and spike voltage. Fast fuses provide short circuit and overload protection.
The international standard of anti conduction will not cause any interference to your power supply.
The international standard of radiation protection can make you healthy and free from worry.
Intelligent no load automatic switch on and shutdown (LCD)
When the power supply is in, the UPS will automatically switch on without any operation and charge the battery at the same time.
The device is in a power-off state when power failure, the system will automatically detect the load, when the load is less than 5%, UPS will be judged as the idle state, 1 minutes after the automatic shutdown, reduce loss, effectively prolong the service life of the battery.
Automatic frequency selection technology
After the UPS is connected to the power supply, the system will automatically adjust the inverter frequency according to the input frequency, so as to relieve the 50/60HZ power supply worries for the users.
