The EA880 low frequency UPS is the second generation digital true double conversion online UPS designed by EAST. It supplies pure and uninterruptible AC power to computers, date centers, network administration centers, other equipment, etc. The system uses DSP technology with good quality power components, lots of auto protection, advanced software management and communication interface, etc.
Features
1. Advanced DSP, Digital Control Technology
The inverter control, phase synchronous, I/P rectify control, logic control systems are utilized in this online UPS, and all of them take advantage of the DSP technology. This UPS has features of high precision, high speed, simplified control circuit and high reliability.
2. High Input Power Factor, Green and Energy-Saving Power
1.) The I/P power factor is above 0.98.
2.) Input current THDI is less than 5%, so it can greatly reduce the humornic pollution of the AC network. At the same time, the efficiency of the usage of the utility is improved so the installation cost and the noise is also reduced.
3.) The speed of the fan is auto-adjustable.
4.) Our UPS is green energy-saving power.
3. Wide Input Voltage and Frequency Range
This EA880 series of online UPS 1/1 3/1 is designed with a wide input voltage and frequency range, so it helps reduce the frequency of battery discharge to prolong the battery life. It can work with an oil generator.
4. Reliable Parallel Technology
With the adoption of the most advanced parallel control technology and digital equal flow control technology, this online UPS is highly compatible and has the choice of N 1 parallel and redundancy and share battery sets.
5. Abundant Interface Setting Functions
The UPS is designed with front panel buttons, making it convenient for the user to set the O/P voltage and frequency. The UPS can be set to connect equipment with different voltage and frequency.
6. Flexible Network Monitoring and Management
1.) The UPS is available with RS232, USB, EPO, optional RS485, optional SNMP, optional dry contact, etc.
2.) It can support TCP/IP protocol with remote control.
3.) Due to network monitoring and management, the UPS has the function of self-diagnosis, sending, in a timely manner, the demanding instruction, email, automatically saving the files, turning off the UPS, etc.
7. Large LCD Display in Both Chinese and English
The EA8800 series UPS comes with a large LCD display to show the working status and technical parameters of the UPS. It gives failure alarm information and reports which makes the daily maintenance of the UPS very easy.
8. Perfect Protection
This kind of UPS is provided with I/P and O/P over-voltage protection, low voltage protection, overload protection, short-circuit protection, over-heat protection, surge protection etc. so the UPS can work in different environments.
9. Cold Start and AC Start Function
The UPS can be started with the battery directly when the AC fails. In AC mode, UPS can be started by AC directly without battery. When the battery discharges and there is low voltage protection, after AC returns, the UPS starts up automatically.
10. Easy Maintenance Design
Our EA880 online UPS is designed with an English display option, manual bypass design, and failure information enquiry orientation. It is convenient to use and improves the usability and maintainability of the system.
Applications
It is used in finance, telecommunications, revenue, traffic, insurance, government, corporations, etc.
