EA880 low frequency UPS is the second generation digital true double conversion on-line UPS designed by EAST; it supplies pure and uninterruptible AC power to computer; date center; network administration center and other equipment etc.The system adopts DSP technology, with good quality power components,lots of auto protection, advanced software management and comminication interface etc. EA880 series UPS can be used in the filed of finance, telecommunication, revenue, traffic, insurance, government, corporation etc.
Advanced DSP---digital control technology
The inverter control, phase synchronous, I/P rectify control, logic control systems all take advantage of the DSP technology so that the UPS has the following features: high precision,high speed; simplified control circuit and high reliability.
High input power factor---green and energy-saving power
The I/P power factor is above 0.98;Input current THDI <5% ,which greatly reduces the humornic pollution of the AC network, and at the meantime, the efficiency of the usage of the utility is improved , and the installation cost and the noise is reduced. The speed of the fan can be auto-adjustable as well; all these make the UPS green energy-saving power.
Wide input voltage and frequency range
With the wide input voltage and frequency range, it reduces the frequency of battery discharge so that the battery life can be prolonged and in the meantime, it can works with oil generator.
Reliable parallel technology
It adopts the most advanced parallel control technology and digital equal flow control technology to make the UPS highly compatible and have the choice of N+1 parallel and redundancy and share battery sets.
Abundant interface setting functions
The user can set the O/P voltage and frequency through the front panel buttons and the UPS can be set to connect equipent with different voltage and frequency.
Flexible network monitoring and management
The UPS is available with RS232, USB, EPO,RS485(optional), SNMP(optional), dry contact(optional) ect.; it can support TCP/IP protocol with remote control; The network monitoring and management enables the UPS to have the function of self-diagnosis, timingly sending the demanding instruction, email, automatically saving the files and turning off the UPS ect..
Large LCD display in both Chinese and English
EA8800 series UPS is equipped with large LCD Display and it shows the working status and technical parameters of the UPS and also gives failure alarm information and report which makes the daily maintenance of the UPS easy.
The UPS has I/P & O/P over-voltage protection, low voltage protection, Overload protection, short-circuit protection, over-heat protection, surge protection etc to make sure the UPS can work in different environment.
Cold start and AC start function
When AC fails, UPS can be started in battery directly;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 can start up automatically.
Easy maintenance design
English display option,manual bypass design,failure information enquiry orientation…all is convenient for user and in the meantime,improving the usability and maintainability of the system.
